  21 m4_dnl each system call has
  22 m4_dnl  hm_syscall(<name>,<returnvalue>,<args>)
  23 m4_dnl <returnvalue> is one of
  24 m4_dnl  hm_rv_must       must succeed and return 0
  25 m4_dnl  hm_rv_any        any nonnegative return allowed, -1 means see errno
  26 m4_dnl  hm_rv_fd         file descriptor is returned, -1 means see errno
  27 m4_dnl  hm_rv_succfail   returns 0 (ok) or -1 (see errno)
  28 m4_dnl  hm_rv_len(<max>) returns length read/written, must be <=max, -1 => errno
  29 m4_dnl  hm_rv_fcntl      syscall is fcntl, do special processing
  30 m4_dnl <args> is list of macros for arguments, each followed by hm_na
  31 m4_dnl  hm_arg_nullptr(<type>,<arg>)    pointer of type type, must be null
  32 m4_dnl  hm_arg_int(<arg>)               signed integer
  33 m4_dnl  hm_arg_fdset_io(<arg>,<max>)    fd_set, max bit set is in max
  34 m4_dnl  hm_arg_timeval_in_rel_null(<t>) struct timeval*, pass in, relative, may be null
  35 m4_dnl  hm_arg_must(<type>,<arg>,<val>) must have correct value, or abort test
  36 m4_dnl  hm_arg_socktype(<arg>)          SOCK_STREAM or SOCK_DGRAM (an int)
  37 m4_dnl  hm_arg_ign(<type>,<arg>)        input parameter ignored
  38 m4_dnl  hm_arg_fd(<arg>)                fd
  39 m4_dnl  hm_arg_fcntl_cmd_arg(<ca>,<aa>) syscall is fcntl, do special processing
  40 m4_dnl  hm_arg_addr_in(<arg>,<len>)     struct sockaddr*, length given by <len> (an int)
  41 m4_dnl  hm_arg_bytes_in(<objtype>,<objarg>,<lentype>,<lenarg>)
  42 m4_dnl   some data from caller; <objarg> is of type pointer to const <objtype>
  43 m4_dnl   and points to <lenarg> bytes (<lenarg> is of type <lentype>)
  44 m4_dnl  hm_arg_bytes_out(<objtype>,<objarg>,<lentype>,<buflenarg>)
  45 m4_dnl   buffer for data from syscall; <objarg> is of type pointer to const <objtype>
  46 m4_dnl   and points to at least <lenarg> bytes (<lenarg> is of type <lentype>)
  47 m4_dnl   return value from syscall is supposed to be returned length
  48 m4_dnl  hm_arg_addr_out(<arg>,<lenptr>) struct sockaddr*, length io at <lenptr> (an int*)
