+ezmlm is an easy-to-use, high-speed mailing list manager for qmail.
+
+ezmlm lets users set up their own mailing lists within qmail's address
+hierarchy. A user, Joe, types
+
+ ezmlm-make ~/SOS ~/.qmail-sos joe-sos isp.net
+
+and instantly has a functioning mailing list, joe-sos@isp.net, with all
+relevant information stored in a new ~/SOS directory.
+
+ezmlm sets up joe-sos-subscribe and joe-sos-unsubscribe for automatic
+processing of subscription and unsubscription requests. Any message to
+joe-sos-subscribe will work; Joe doesn't have to explain any tricky
+command formats. ezmlm will send back instructions if a subscriber sends
+a message to joe-sos-request or joe-sos-help.
+
+ezmlm automatically archives new messages. Messages are labelled with
+sequence numbers; a subscriber can fetch message 123 by sending mail to
+joe-sos-get.123. The archive format supports fast message retrieval even
+when there are thousands of messages.
+
+ezmlm takes advantage of qmail's VERPs to reliably determine the
+recipient address and message number for every incoming bounce message.
+It waits ten days and then sends the subscriber a list of message
+numbers that bounced. If that warning bounces, ezmlm sends a probe; if
+the probe bounces, ezmlm automatically removes the subscriber from the
+mailing list.
+
+ezmlm is easy for users to control. Joe can edit ~/SOS/text/* to change
+any of the administrative messages sent to subscribers. He can remove
+~/SOS/public and ~/SOS/archived to disable automatic subscription and
+archiving. He can put his own address into ~/SOS/editor to set up a
+moderated mailing list. He can edit ~/SOS/{headeradd,headerremove} to
+control outgoing headers. ezmlm has several utilities to manually
+inspect and manage mailing lists.
+
+ezmlm uses Delivered-To to stop forwarding loops, Mailing-List to
+protect other mailing lists against false subscription requests, and
+real cryptographic cookies to protect normal users against false
+subscription requests. ezmlm can also be used for a sublist,
+redistributing messages from another list.
+
+ezmlm is reliable, even in the face of system crashes. It writes each
+new subscription and each new message safely to disk before it reports
+success to qmail.
+
+ezmlm doesn't mind huge mailing lists. Lists don't even have to fit into
+memory. ezmlm hashes the subscription list into a set of independent
+files so that it can handle subscription requests quickly. ezmlm uses
+qmail for blazingly fast parallel SMTP deliveries.

+Like any other piece of software (and information generally), ezmlm
+comes with NO WARRANTY.
+
+
+Things you have to decide before starting:
+
+* Where programs will be installed, normally /usr/local/bin/ezmlm. To
+change this directory, edit conf-bin now.
+
+* Where man pages will be installed, normally /usr/local/man. To change
+this directory, edit conf-man now.
+
+* Where the qmail home directory is, normally /var/qmail. To change this
+directory, edit conf-qmail now.
+
+
+How to install:
+
+ 1. Compile the programs:
+ % make
+ 2. Format the man pages:
+ % make man
+ 3. Install the programs and man pages:
+ # make setup
+
+
+How to test:
+
+ 4. Make sure ezmlm-make is in your path. Create a mailing list:
+ % ezmlm-make ~/testlist ~/.qmail-testlist me-testlist host
+ Replace ``me'' and ``host'' with your e-mail address.
+ 5. Subscribe yourself to the list manually:
+ % ezmlm-sub ~/testlist me@host
+ 6. Send a message to the list:
+ % echo subject:testing | qmail-inject me-testlist@host
+ You should receive a copy of the message at me@host.
+ 7. View the list membership:
+ % ezmlm-list ~/testlist
+ You should see just one line, containing your address.
+ 8. Unsubscribe yourself through e-mail:
+ % qmail-inject me-testlist-unsubscribe@host < /dev/null
+ When you receive the confirmation number, reply to complete your
+ unsubscription. Use ezmlm-list to check that the list is empty.
+ 9. Retrieve the first message from the archive:
+ % qmail-inject me-testlist-get.1@host < /dev/null
+ You should receive a copy of your subject:testing message.
+
+
+That's it! To report success:
+ % ( echo 'First M. Last'; cat `cat SYSDEPS` ) \
+ | mail djb-qst@koobera.math.uic.edu
+Replace First M. Last with your name.

+.SH DESCRIPTION
+.B alloc
+allocates enough space from the heap for
+.I new
+bytes of data,
+adequately aligned for any data type.
+.I new
+may be 0.
+.B alloc
+returns a pointer to the space.
+If space is not available,
+.B alloc
+returns 0,
+setting
+.B errno
+appropriately.
+
+.B alloc_free
+returns space to the heap.
+
+.B alloc_re
+expands the space allocated to
+.I x
+from
+.I old
+bytes to
+.I new
+bytes.
+It allocates new space,
+copies
+.I old
+bytes from the old space to the new space,
+returns the old space to the heap,
+and changes
+.I x
+to point to the new space.
+It then returns 1.
+If space is not available,
+.B alloc_re
+returns 0,
+leaving the old space alone.

+.SH DESCRIPTION
+International Atomic Time, TAI,
+is the fundamental unit for time measurements.
+TAI has one label for every second of real time,
+without complications such as leap seconds.
+
+A
+struct datetime
+variable,
+such as
+.IR dt ,
+stores a TAI label.
+.I dt\fB.year
+is the year number minus 1900;
+.I dt\fB.mon
+is the month number, from 0 (January) through 11 (December);
+.I dt\fB.mday
+is the day of the month, from 1 through 31;
+.I dt\fB.hour
+is the hour, from 0 through 23;
+.I dt\fB.min
+is the minute, from 0 through 59;
+.I dt\fB.sec
+is the second, from 0 through 59;
+.I dt\fB.wday
+is the day of the week, from 0 (Sunday) through 6 (Saturday);
+.I dt\fB.yday
+is the day of the year, from 0 through 365.
+
+The
+.B datetime
+library supports more convenient TAI manipulation with
+the datetime_sec type.
+A datetime_sec value, such as
+.IR t ,
+is an integer referring to the
+.IR t th
+second after the beginning of 1970 TAI.
+The first second of 1970 TAI was 0;
+the next second was 1;
+the last second of 1969 TAI was -1.
+The difference between two datetime_sec values is a number
+of real-time seconds.
+
+.B datetime_tai
+converts a datetime_sec to a TAI label.
+
+.B datetime_untai
+reads a TAI label
+(specifically
+.IR dt\fB.year ,
+.IR dt\fB.mon ,
+.IR dt\fB.mday ,
+.IR dt\fB.hour ,
+.IR dt\fB.min ,
+and
+.IR dt\fB.sec )
+and returns a datetime_sec.

+.B ezmlm-manage
+.I dir
+.SH DESCRIPTION
+.B ezmlm-manage
+handles administrative requests for the mailing list
+stored in
+.IR dir .
+
+.B ezmlm-manage
+is normally invoked from a
+.B .qmail
+file.
+It reads a mail message from its standard input,
+and a mail envelope from the
+.BR SENDER ,
+.BR LOCAL ,
+and
+.BR HOST
+environment variables.
+
+.B ezmlm-manage
+expects
+.B LOCAL
+to be of the form
+.IR list\fB-\fIaction\fB-\fIbox\fB=\fIdomain .
+Here
+.I list
+is the first line of
+.IR dir\fB/inlocal ,
+.I action
+is a request,
+and
+.I box\fB@\fIdomain
+is the target of the request.
+.B ezmlm-manage
+sends a response to the target.
+It attaches the original message to the end of its response.
+
+.B LOCAL
+may instead be of the form
+.IR list\fB-\fIaction .
+Then the envelope sender
+is used as the target.
+
+.B ezmlm-manage
+expects
+.B HOST
+to match the first line of
+.IR dir\fB/inhost .
+
+.B ezmlm-manage
+copies
+.I dir\fB/mailinglist
+into a

+is an appropriate code
+(depending on the target, the approximate time, and other factors),
+.B ezmlm-manage

+.BR subscribe ,
+.B ezmlm-manage
+does not subscribe the target,
+but it identifies the right
+.BR sc.\fIcookie
+address in its response.
+
+This confirmation mechanism
+(1) verifies that the target is reachable
+and
+(2) protects the target against forged subscription requests.
+
+Actions of

+are used in the same way to delete the target from the mailing list.

+.TH ezmlm-send 1
+.SH NAME
+ezmlm-send \- distribute a message to a mailing list
+.SH SYNOPSIS
+.B ezmlm-send
+.I dir
+.SH DESCRIPTION
+.B ezmlm-send
+reads a mail message and
+sends it to the mailing list stored in
+.IR dir .
+If
+.I dir\fB/archived
+exists,
+.B ezmlm-send
+records a copy of the message in the
+.I dir\fB/archive
+directory.
+
+At the beginning of the message,
+.B ezmlm-send
+prints a new
+.B Mailing-List
+field with the contents of
+.IR dir\fB/mailinglist .
+It rejects the message if there is already a
+.B Mailing-List
+field.
+
+.B ezmlm-send
+then prints all the new fields listed in
+.IR dir\fB/headeradd ,
+followed by an appropriate
+.B Delivered-To
+line.
+
+.B ezmlm-send
+deletes any incoming fields with names listed in
+.IR dir\fB/headerremove .
+
+.B ezmlm-send
+does not distribute bounce messages:
+if the environment variable
+.B SENDER
+is set, and is either empty or
+.BR #@[] ,
+.B ezmlm-send
+rejects the message.
+.SH "SUBLISTS"
+If
+.I dir\fB/sublist
+exists,
+.B ezmlm-send
+changes its behavior in several ways.
+
+First, if
+.B SENDER
+is set,
+and the first line of
+.I dir\fB/sublist
+has the form
+.IR parent\fB@\fIparenthost ,
+.B ezmlm-send
+insists that
+.B SENDER
+have the form
+.IR parent\fB...@\fIparenthost .
+
+Second,
+.B ezmlm-send
+demands that the message already have a
+.B Mailing-List
+field.
+
+Third,
+.B ezmlm-send
+does not add its own
+.B Mailing-List
+field.
+.SH "SEE ALSO"
+ezmlm-manage(1),
+ezmlm-make(1),
+ezmlm-sub(1),
+ezmlm-unsub(1),
+ezmlm-reject(1),
+ezmlm(5)

+.SH NAME
+ezmlm \- format of ezmlm directory
+.SH OVERVIEW
+An
+.B ezmlm
+directory,
+.IR dir ,
+stores information about an
+.B ezmlm
+mailing list.
+.B ezmlm-make
+creates
+.IR dir ;
+.B ezmlm-sub
+and
+.B ezmlm-unsub
+manipulate the subscriber list stored under
+.IR dir ;
+.B ezmlm-manage
+handles administrative requests automatically;
+.B ezmlm-send
+sends a message to all subscribers listed in
+.IR dir .
+.SH SUBSCRIBERS
+.I dir\fB/subscribers
+is a directory containing the subscriber list.
+.B ezmlm-manage
+allows automatic subscription if
+.I dir\fB/public
+exists.
+
+The list is hashed into 53 files, named
+.B @
+through
+.B t
+in ASCII.
+A nonexistent file is treated as an empty file.
+
+Each file contains a series of addresses.
+An address can be any string of non-NUL characters up to 400 bytes long.
+Each address is preceded by the letter T and followed by a NUL.
+
+For reliability,
+when an address is added to or removed from the mailing list,
+the relevant file is recreated under a temporary name
+inside
+.I dir\fB/subscribers
+and then moved into place.
+
+.I dir\fB/key
+is a binary file.
+.B ezmlm-manage
+uses
+.I dir\fB/key
+to create confirmation numbers.
+Anyone who can guess the contents of
+.I dir\fB/key
+can forge subscription requests.
+.B ezmlm-make
+does not put much effort into making
+.I dir\fB/key
+difficult to guess;
+for better security, you should add some random garbage to
+.IR dir\fB/key .
+.SH ARCHIVE
+.I dir\fB/archive
+is a directory containing messages previously sent to subscribers.
+.B ezmlm-send
+archives all new messages if
+.I dir\fB/archived
+exists.
+
+Messages sent to the mailing list are numbered from 1 upwards,
+whether or not they are archived.
+.I dir\fB/num
+is the number of messages sent so far.
+
+.I dir\fB/archive
+has subdirectories,
+each subdirectory storing up to 100 messages.
+Message number 100m+n, with n between 0 and 99, is stored in
+.IR dir\fB/archive/\fIm\fB/\fIn .
+For example, message number 15307 is stored in
+.IR dir\fB/archive/153/07 .
+
+.B ezmlm-manage
+will ignore message files without the owner-execute bit set.
+.B ezmlm-send
+turns on the owner-execute bit after safely writing the message to disk.
+.SH BOUNCES
+.I dir\fB/bounce
+is a directory containing bounce messages.
+.B ezmlm-return
+stores several types of files here.
+.SH "DELIVERY INSTRUCTIONS"
+.B ezmlm-make
+sets up four files to control mailing list deliveries.
+Each file is a series of delivery instructions in
+.B dot-qmail
+format.
+
+.I dir\fB/editor
+handles incoming mailing list submissions.
+.B ezmlm-make
+sets up
+.I dir\fB/editor
+to invoke
+.B ezmlm-send
+to immediately forward each message to all subscribers
+and then to run
+.BR ezmlm-warn .
+
+.I dir\fB/owner
+handles incoming messages for the mailing list's owner.
+.B ezmlm-make
+sets up
+.I dir\fB/owner
+to store messages in
+.I dir\fB/Mailbox
+and then to run
+.BR ezmlm-warn .
+
+.I dir\fB/bouncer
+handles incoming bounce messages.
+.B ezmlm-make
+sets up
+.I dir\fB/bouncer
+to invoke
+.B ezmlm-return
+and then
+.BR ezmlm-warn .
+
+.I dir\fB/manager
+handles incoming administrative requests.
+.B ezmlm-make
+sets up
+.I dir\fB/manager
+to invoke
+.B ezmlm-manage
+and then
+.BR ezmlm-warn .
+.SH TEXT
+.I dir\fB/text
+is a directory
+containing files sent out by
+.B ezmlm-manage
+in response to administrative requests:
+.TP 15
+.B top
+Introducing
+.BR ezmlm .
+This is placed at the top of each response.
+.TP
+.B bottom
+Explaining how to use
+.BR ezmlm .
+This is placed at the bottom of each response.
+.TP
+.B sub-confirm
+Explaining how to confirm a subscription request.
+.TP
+.B sub-ok
+Acknowledging successful subscription.
+.TP
+.B sub-nop
+Acknowledging a subscription request for an address already
+on the mailing list.
+.TP
+.B sub-bad
+Rejecting a bad subscription confirmation number.
+.TP
+.B unsub-confirm
+Explaining how to confirm an unsubscription request,
+and explaining how to figure out the subscription address.
+.TP
+.B unsub-ok
+Acknowledging successful unsubscription.
+.TP
+.B unsub-nop
+Acknowledging an unsubscription request for an address not
+on the mailing list.
+.TP
+.B unsub-bad
+Rejecting a bad unsubscription confirmation number.
+.TP
+.B get-bad
+Rejecting a bad archive retrieval request.
+.TP
+.B bounce-warn
+Pointing out that messages have bounced.
+.TP
+.B bounce-probe
+Pointing out that a warning message has bounced.
+.TP
+.B bounce-num
+Explaining that
+.B ezmlm-return
+has kept a list of bounced message numbers.
+.TP
+.B bounce-bottom
+Separating the bounce message.
+.PP
+.B ezmlm-manage
+replaces the line
+.B !A
+in any of these files
+with the name of the subscription address.
+It replaces the line
+.B !R
+in
+.B sub-confirm
+and
+.B unsub-confirm
+with the address that the subscriber must reply to.
+.SH "OUTGOING MESSAGE EDITING"
+.I dir\fB/headerremove
+is a list of bad header field names,
+one per line.
+.B ezmlm-send
+removes these header fields from all outgoing messages.
+.B ezmlm-make
+sets up
+.I dir\fB/headerremove
+to remove
+.BR Return-Path ,
+.BR Return-Receipt-To ,
+and
+.B Return-Path
+fields.
+
+.I dir\fB/headeradd
+is a list of new header fields.
+.B ezmlm-send
+adds these fields to every outgoing message.
+.B ezmlm-make
+sets up
+.I dir\fB/headeradd
+with no new fields.
+.SH MISCELLANY
+The first line of
+.I dir\fB/mailinglist
+is a line of text.
+.B ezmlm-send
+creates a new
+.B Mailing-List
+field, showing the contents of
+.IR dir\fB/mailinglist ,
+in every outgoing message.
+
+The first lines of
+.I dir\fB/outlocal
+and
+.I dir\fB/outhost
+give the outgoing name of the mailing list.
+These are used by
+.B ezmlm-manage
+and
+.B ezmlm-send
+to construct sender addresses for outgoing messages.
+
+The first lines of
+.I dir\fB/inlocal
+and
+.I dir\fB/inhost
+give the incoming name of the mailing list.
+These are used by
+.B ezmlm-manage
+to parse incoming envelopes.
+Normally
+.I inlocal
+and
+.I inhost
+are the same as
+.I outlocal
+and
+.IR outhost ,
+but sometimes they are different,
+with
+.I outlocal\fB@\fIouthost
+forwarded to
+.IR inlocal\fB@\fIinhost .
+
+If
+.I dir\fB/sublist
+exists,
+this mailing list is a sublist,
+redistributing messages from a parent mailing list.
+The first line of
+.I dir\fB/sublist
+is the name of the parent list.
+This affects the behavior of
+.BR ezmlm-send .
+
+.I dir\fB/lock
+is an empty file.
+Any program that reads or writes the subscriber list,
+or adds messages to the archive,
+locks
+.IR dir\fB/lock .
+
+.I dir\fB/Log
+is an advisory log of subscription and unsubscription actions.
+.B WARNING:
+.B Log
+is not protected against system crashes.
+Log entries may be missing or corrupted if the system goes down.

+.SH DESCRIPTION
+.B getln2
+reads a line of characters, terminated by a
+.I sep
+character,
+from
+.IR ss .
+
+The line is returned in two pieces.
+The first piece is stored in
+.IR sa .
+The second piece is
+.IR cont ,
+a pointer to
+.I clen
+characters inside the
+.I ss
+buffer.
+The second piece must be copied somewhere else
+before
+.I ss
+is used again.
+
+If
+.B getln2
+sees end-of-input before it sees
+.IR sep ,
+it sets
+.I clen
+to 0 and does not set
+.IR cont .
+It puts the partial line into
+.IR sa .
+
+.B getln2
+normally returns 0.
+If it runs out of memory,
+or encounters an error from
+.IR ss ,
+it returns -1,
+setting
+.B errno
+appropriately.

+.SH DESCRIPTION
+This is a clone version of
+the standard
+.B getopt
+library,
+built on top of
+.BR subgetopt(3) .
+
+See
+.B subgetopt(3)
+for a detailed description of
+.B getopt
+processing.
+The main difference between
+.B getopt
+and
+.B subgetopt
+is that
+.B getopt
+prints error messages
+in case of problems.
+To turn off these error messages, set
+.B opterr
+(default nonzero)
+to zero.
+
+This clone version of
+.B getopt
+also provides an
+.B optprogname
+variable.
+There are two uses for this variable:
+
+(1)
+By default
+.B optprogname
+is null.
+When
+.B getopt
+sees this,
+it
+attempts to initialize
+.B optprogname
+from
+.IR argv\fB[0] ,
+stripping the directory name.
+The calling program can use
+.B optprogname
+after calling
+.B getopt
+at least once.
+This is appropriate if the name of the program should be
+determined from its command line.
+
+(2)
+.B getopt
+prints
+.B optprogname
+at the beginning
+of any error messages.
+So the calling program can,
+before calling
+.BR getopt ,
+initialize
+.B optprogname
+as desired.
+This is appropriate if the name of the program should not be
+determined from its command line.
+.SH "COMPATIBILITY"
+Old versions of
+.B getopt
+do not include
+.BR opterr .
+.BR optpos ,
+.BR opteof ,
+.BR optproblem ,
+and
+.B optprogname
+are specific to this clone version of
+.BR getopt .
+
+Many features of this clone version of
+.B getopt
+are poorly defined, if available at all,
+in most versions of
+.BR getopt .
+For example, the standard
+.B getopt
+interface does not define
+.B optind
+until the end of the option list.
+And
+.B optarg
+is not defined
+unless
+.B getopt
+has just returned
+an option which takes an argument.
+In this clone version,
+.B optind
+and
+.B optpos
+always indicate the next character to be read,
+and
+.B optarg
+is null whenever
+the current option does not take an argument.
+See
+.B subgetopt(3)
+for precise definitions of the parsing procedure.
+
+When it reaches the end of the option list,
+this version of
+.B getopt
+always returns
+.BR opteof ,
+which is the same as
+.BR subgetoptdone ,
+which is initialized to
+.BR SUBGETOPTDONE ,
+which is defined as \-1.
+The standard behavior is to return
+EOF
+from
+.B stdio(3).
+This is incompatible
+on any weird machine where
+EOF is different from \-1.
+The calling program could set
+.B opteof
+to EOF to imitate the standard behavior.
+
+Like most versions of
+.BR getopt ,
+this clone version allows, but does not demand, that
+option arguments be
+separated from the option by whitespace, i.e., be
+in the next command-line argument.
+
+Some versions of
+.B getopt
+provide an
+.B optopt
+variable.
+.B optopt
+is incompatible across systems:
+for example,
+GNU
+.B getopt
+uses it the same way that this clone version uses
+.BR optproblem ,
+while
+BSD
+.B getopt
+uses it to
+indicate the last option character returned by
+.BR getopt .
+This clone version does not provide
+.BR optopt .
+The use of
+.B optopt
+is strongly discouraged.
+
+Some versions of
+.B getopt
+do not recognize a double hyphen as the end of arguments.
+This version allows a double hyphen, or in fact any argument beginning
+with two hyphens.
+
+A lone hyphen is always recognized as the end of arguments.
+Some versions of
+.B getopt
+allow lone hyphens as options.
+This practice is wrong and is strongly discouraged.
+.SH "SYNTAX NOTE"
+.B getopt
+is actually a macro abbreviation for
+.BR getoptmine .
+The external
+.B opterr
+and
+.B optprogname
+variables
+are macros for
+.B getopterr
+and
+.BR getoptprogname .
+All the other
+.B opt
+variables are macros
+for
+.BR subgetopt .
+These macros are defined in
+.BR <getopt.h> ,
+unless
+.B GETOPTNOSHORT
+is defined.
+Further macros are defined in
+.BR <subgetopt.h> ,
+which is included by
+.BR <getopt.h> ,
+unless
+.B SUBGETOPTNOSHORT
+is defined.

+.SH DESCRIPTION
+A
+.B stralloc
+variable holds a string in dynamically allocated space.
+String length is limited only by memory.
+String contents are unrestricted.
+
+The
+.B stralloc
+structure has three components:
+.I sa\fB.s
+is a pointer to the string, or 0 if it is not allocated;
+.I sa\fB.len
+is the number of bytes in the string, if it is allocated;
+.I sa\fB.a
+is the number of bytes allocated for the string, if it is allocated.
+A
+.B stralloc
+variable should be initialized to {0},
+meaning unallocated.
+
+.B stralloc_ready
+makes sure that
+.I sa
+has enough space allocated for
+.I len
+characters.
+It allocates extra space if necessary.
+
+.B stralloc_readyplus
+makes sure that
+.I sa
+has enough space allocated for
+.I len
+characters more than its current length.
+If
+.I sa
+is unallocated,
+.B stralloc_readyplus
+is the same as
+.BR stralloc_ready .
+
+.B stralloc_copy
+copies
+.I sa2
+to
+.IR sa ,
+allocating space if necessary.
+Here
+.I sa2
+is an allocated
+.B stralloc
+variable.
+
+.B stralloc_copys
+copies a 0-terminated string,
+.IR buf ,
+to
+.IR sa ,
+without the 0.
+
+.B stralloc_copyb
+copies
+.I len
+characters from
+.I buf
+to
+.IR sa .
+
+.B stralloc_cat
+appends
+.I sa2
+to
+.IR sa ,
+allocating space if necessary.
+If
+.I sa
+is unallocated,
+.B stralloc_cat
+is the same as
+.BR stralloc_copy .
+
+.B stralloc_cats
+and
+.B stralloc_catb
+are analogous to
+.B stralloc_copys
+and
+.BR stralloc_copyb .
+
+.B stralloc_append
+adds a single character,
+.IR *buf ,
+to
+.IR sa ,
+allocating space if necessary.
+
+.B stralloc_0
+adds a single 0 character
+to
+.IR sa .
+
+.B stralloc_starts
+returns 1 if the 0-terminated string
+.IR buf ,
+without the 0,
+is a prefix of
+.IR sa .
+.SH "ERROR HANDLING"
+If a
+.B stralloc
+routine runs out of memory,
+it leaves
+.I sa
+alone and returns 0,
+setting
+.B errno
+appropriately.
+On success it returns 1;
+this guarantees that
+.I sa
+is allocated.

+.SH DESCRIPTION
+.B sgopt
+returns the next valid command-line option character
+from
+.IR argv .
+
+Valid option characters are listed in the
+.I opts
+string.
+.I opts
+may be empty.
+A character in
+.I opts
+may be followed by a colon,
+in which case it
+takes an
+.I option argument\fR.
+Avoid using the characters ?, :, and \- as option characters.
+
+Below
+.I option argument
+is abbreviated
+as
+.I optarg
+and
+.I command-line argument
+is abbreviated as
+.IR cmdarg .
+
+Options are listed in cmdargs which begin with
+a minus sign.
+Several options which do not take optargs may be combined
+into one cmdarg.
+
+An option which takes an optarg may be handled in two ways.
+If it appears at the very end of a cmdarg,
+then the entire next cmdarg is the optarg.
+But if there are any characters in the cmdarg
+after the option character,
+then those characters form the optarg.
+The optarg is returned in
+.BR sgoptarg .
+Next time
+.B sgopt
+looks at the cmdarg which follows the optarg.
+
+If a cmdarg does not begin with a hyphen,
+or if it is a lone hyphen not followed by any characters,
+or if it begins with two hyphens,
+then it terminates option processing,
+and
+.B sgopt
+returns an appropriate code.
+If there are two hyphens,
+.B sgopt
+will advance attention to the next cmdarg,
+so it can be called again to read further options.
+.SH "PROPER USAGE"
+.B sgoptproblem
+should be used only when
+.B sgopt
+returns ?.
+.B sgoptind
+and
+.B sgoptpos
+are defined all the time.
+.B sgoptarg
+is defined all the time;
+it is null unless
+.B sgopt
+has just returned an option with optarg.
+
+.B sgopt
+is typically used as follows.
+
+.EX
+#include <subgetopt.h>
+
+main(argc,argv) int argc; char **argv; { int opt;
+
+while ((opt = sgopt(argc,argv,"a:s")) != sgoptdone)
+.br
+ switch(opt) {
+.br
+ case 'a':
+.br
+ printf("opt a with optarg %s\\n",sgoptarg); break;
+.br
+ case 's':
+.br
+ printf("opt s with no optarg\\n"); break;
+.br
+ case '?':
+.br
+ if (argv[sgoptind] && (sgoptind < argc))
+.br
+ printf("illegal opt %c\\n",sgoptproblem);
+.br
+ else
+.br
+ printf("missing arg, opt %c\\n",sgoptproblem);
+.br
+ exit(1);
+.br
+ }
+
+argv += sgoptind;
+.br
+while (*argv) printf("argument %s\\n",*argv++);
+.br
+exit(0);
+.br
+}
+.EE
+
+The end of the command line is
+marked by either
+.IR argc ,
+or a null pointer in
+.IR argv ,
+whichever comes first.
+Normally
+these two markers coincide,
+so it is redundant
+to test for
+both
+.I argv\fB[sgoptind]
+and
+.B sgoptind < \fIargc\fR.
+The above code shows both tests as an illustration.
+
+.B Multiple option sets:
+One useful technique is to call
+.B sgopt
+with a primary
+.I opts
+until it returns EOF,
+then call
+.B sgopt
+with a secondary
+.I opts
+until it returns EOF.
+The user can provide primary options, then a double hyphen,
+and then secondary options.
+No special handling is needed if some or all of the options are
+omitted.
+The same technique can be used for any number of option sets
+in series.
+
+.B Multiple command lines:
+Before parsing a new
+.BR argv ,
+make sure to
+set
+.B sgoptind
+and
+.B sgoptpos
+back to
+1 and 0.
+.SH "PARSING STAGES"
+.B sgopt
+keeps track of its position in
+.I argv
+with
+.B sgoptind
+and
+.BR sgoptpos ,
+which are initialized to 1 and 0.
+It looks at
+.I argv\fB[sgoptind][sgoptpos]
+and following characters.
+
+.B sgopt
+indicates
+that no more options are available by
+returning
+.BR sgoptdone ,
+which is initialized to
+.BR SUBGETOPTDONE ,
+which is defined as \-1.
+
+.B sgopt
+begins by setting
+.B optarg
+to null.
+
+.B Ending conditions:
+If
+.I argv
+is null, or
+.B sgoptind
+is larger than
+.IR argc ,
+or the current cmdarg
+.I argv\fB[sgoptind]
+is null,
+then
+.B sgopt
+returns
+.BR optdone .
+
+.B Stage one:
+If the current character
+is zero,
+.B sgopt
+moves to the beginning of the next cmdarg.
+It then checks the ending conditions again.
+
+.B Stage two:
+If
+the current position is the begining of the cmdarg,
+.B sgopt
+checks whether
+the current character
+is a minus sign.
+If not it returns
+.BR optdone .
+It then
+moves
+to the next character.
+If that character is zero,
+.B sgopt
+moves
+back to the beginning of the cmdarg,
+and returns
+.BR sgoptdone .
+If the character is a minus sign,
+.B sgopt
+moves to the beginning of the next cmdarg,
+and returns
+.BR sgoptdone .
+
+.B Stage three:
+.B sgopt
+records the current character,
+.IR c ,
+and moves to the next character.
+There are three possibilities:
+(1)
+.I c
+is an option character without optarg in
+.IR opts ,
+or
+(2)
+.I c
+is an option character with optarg in
+.IR opts ,
+or
+(3)
+.I c
+does not appear in
+.IR opts .
+
+(1)
+If
+.I c
+appears as an option character without optarg in
+.IR opts ,
+.B sgopt
+returns
+.IR c .
+
+(2)
+If
+.I c
+appears as an option character with optarg in
+.IR opts ,
+.B sgopt
+sets
+.B sgoptarg
+to the current position,
+and moves to the next cmdarg.
+If
+.B sgoptarg
+is nonempty,
+.B sgopt
+returns
+.IR c .
+
+Then
+.B sgopt
+sets
+.B sgoptarg
+to
+the current cmdarg.
+If
+the current cmdarg is null,
+or past
+.IR argc ,
+.B sgopt
+sets
+.B sgoptproblem
+to
+.I c
+and returns ?.
+Otherwise
+.B sgopt
+moves to the next
+argument
+and returns
+.IR c .
+
+(2)
+If
+.I c
+does not appear in
+.IR opts ,
+.B sgopt
+sets
+.B sgoptproblem
+to
+.I c
+and returns ?.

+.SH DESCRIPTION
+.B substdio
+is the Sub-Standard I/O Library.
+.B substdio
+contains only a few of the features of stdio;
+it is a fast, lightweight, low-level library,
+suitable for use as a component of higher-level I/O libraries.
+
+The point of
+.B substdio
+is to provide buffered I/O.
+The basic object in
+.B substdio
+is the
+.B substdio
+structure;
+a
+.B substdio
+variable stores
+an operation,
+a descriptor,
+and
+a pointer into a buffer of some nonzero length.
+The
+.B substdio
+operations read data from the buffer,
+filling the buffer as necessary using the operation on the descriptor,
+or write data to the buffer,
+flushing the buffer as necessary using the operation on the descriptor.
+Input and output operations cannot be mixed.
+
+.B substdio_fdbuf
+initializes a
+.B substdio
+variable.
+The operation is
+.IR op .
+The descriptor is
+.IR fd .
+The buffer is
+.IR buf ,
+an array of
+.I len
+chars.
+
+.I op
+will be called as
+.I op\fR(\fIfd\fR,\fIx\fR,\fIn\fR).
+Here
+.I x
+is a pointer to an array of characters of length
+.IR n ;
+.I op
+must read some characters from
+.I fd
+to that array, or write some characters to
+.I fd
+from that array.
+The return value from
+.I op
+must be the number of characters read or written.
+0 characters read means end of input;
+0 characters written means that the write operation
+should be tried again immediately.
+On error,
+.I op
+must return -1,
+setting
+.B errno
+appropriately, without reading or writing anything.
+Most errors are returned directly to the
+.B substdio
+caller, but an error of
+.B error_intr
+means that the operation should be tried again immediately.
+
+There is a
+.B SUBSTDIO_FDBUF
+macro that can be used to statically initialize a
+.B substdio
+variable:
+
+.EX
+ substdio s = SUBSTDIO_FDBUF(op,fd,buf,len);
+.EE
+
+.B substdio_fileno
+returns the
+descriptor for an initialized
+.B substdio
+variable.

+.B substdio_get
+reads at most

+into the character array

+It returns the number of characters read,
+0 for end of file,
+or -1 for error,
+setting
+.B errno
+appropriately.
+
+.B substdio_bget
+has the same function as
+.BR substdio_get .
+The difference is what happens when there is no buffered data and
+.I len
+exceeds the buffer size:
+.B substdio_get
+tries to read
+.I len
+characters, whereas
+.B substdio_bget
+tries to read one buffer of characters.
+In some cases
+.B substdio_bget
+will be more efficient than
+.BR substdio_get .
+
+.B substdio_feed
+makes sure that there is buffered data,
+so that the next
+.B substdio_get
+or
+.B substdio_bget
+will succeed.
+If the buffer is empty,
+.B substdio_feed
+tries to fill it;
+it returns 0 for end of file, -1 for error,
+or the number of buffered characters on success.
+If the buffer already had data,
+.B substdio_feed
+leaves it alone and returns the number of buffered characters.
+
+.B substdio_peek
+returns a pointer to the buffered data.
+
+.B substdio_seek
+throws away
+.I len
+buffered characters,
+as if they had been read.
+.I len
+must be at least 0 and at most the amount of buffered data.
+
+The
+.B substdio_PEEK
+and
+.B substdio_SEEK
+macros behave the same way as
+.B substdio_peek
+and
+.B substdio_seek
+but may evaluate their arguments several times.
+
+The point of
+.B substdio_peek
+and
+.B substdio_seek
+is to read data without unnecessary copies.
+Sample code:
+
+.EX
+ for (;;) {
+.br
+ n = substdio_feed(s);
+.br
+ if (n <= 0) return n;
+.br
+ x = substdio_PEEK(s);
+.br
+ handle(x,n);
+.br
+ substdio_SEEK(s,n);
+.br
+ }
+.EE
+
+The
+.B SUBSTDIO_INSIZE
+macro is defined as a reasonably large input buffer size for
+.BR substdio_fdbuf .
+.SH "INTERNALS"
+When a
+.B substdio
+variable
+.I s
+is used for input,
+there is free buffer space from
+.I s\fB.x
+to
+.I s\fB.x\fR +

+It returns 0 on success, -1 on error.
+
+.B substdio_bput
+has the same function as

+The difference is how the buffer is flushed
+when there isn't enough room for

+characters:
+.B substdio_put
+flushes the buffered data before copying the new data,
+whereas
+.B substdio_bput
+fills the buffer with new data before flushing.
+
+.B substdio_flush
+forces all data to be written from the internal buffer.
+It returns 0 on success, -1 on error.
+
+.B substdio_putflush
+is similar to
+.B substdio_put
+followed by
+.BR substdio_flush ,
+but it avoids all internal copies.
+
+.BR substdio_puts ,
+.BR substdio_bputs ,
+and

+are the same as

+except that

+must be a 0-terminated string of characters.
+The string, not including the 0, is written.

+.SH DESCRIPTION
+.B surfpcs
+converts a character string to a 256-bit output,
+under control of a 1024-bit seed.
+When the seed is secret,
+.B surfpcs
+appears to be indistinguishable from a completely random
+variable-length-to-256-bit function.
+
+Applying
+.B surfpcs
+takes three steps.
+First, initialize a
+.B surfpcs
+variable,
+.IR s ,
+with
+.BR surfpcs_init .
+The seed will be recorded inside
+.IR s .
+
+Second, feed the input to
+.BR surfpcs_add .
+.I buf
+is a pointer to
+.I len
+characters of input.
+You can split the input across any number of
+.B surfpcs_add
+calls.
+
+Third, call
+.BR surfpcs_out .
+The output will be placed into
+.IR h ,
+an array of
+.B SURFPCS_LEN
+bytes.
+.B SURFPCS_LEN
+is 32.
+
+To apply
+.B surfpcs
+to another input you must call
+.B surfpcs_init
+again.

+.SH DESCRIPTION
+.B wait_nohang
+looks for zombies (child processes that have exited).
+If it sees a zombie,
+it eliminates the zombie,
+puts the zombie's exit status into
+.IR wstat ,
+and returns the zombie's process ID.
+If there are several zombies,
+.B wait_nohang
+picks one.
+If there are children but no zombies,
+.B wait_nohang
+returns 0.
+If there are no children,
+.B wait_nohang
+returns -1,
+setting
+.B errno
+appropriately.
+
+.B wait_stopnohang
+is similar to
+.BR wait_nohang ,
+but it also looks for children that have stopped.
+
+.B wait_stop
+is similar to
+.BR wait_stopnohang ,
+but if there are children it will pause waiting for one of them
+to stop or exit.
+
+.B wait_pid
+waits for child process
+.I pid
+to exit.
+It eliminates any zombie that shows up in the meantime,
+discarding the exit status.
+
+.B wait_stop
+and
+.B wait_pid
+retry upon
+.BR error_intr .
+.SH "STATUS PARSING"
+If the child stopped,
+.B wait_stopped
+is nonzero;
+.B wait_stopsig
+is the signal that caused the child to stop.
+
+If the child exited by crashing,
+.B wait_stopped
+is zero;
+.B wait_crashed
+is nonzero.
+
+If the child exited normally,
+.B wait_stopped
+is zero;
+.B wait_crashed
+is zero;
+and
+.B wait_exitcode
+is the child's exit code.
