25 | m4_dnl each system call has |
73c4c523 |
26 | m4_dnl hm_syscall(<name>,<returnvalue>,<args>) |
bb7ba677 |
27 | m4_dnl <returnvalue> is one of |
28 | m4_dnl hm_rv_must must succeed and return 0 |
29 | m4_dnl hm_rv_any any nonnegative return allowed, -1 means see errno |
30 | m4_dnl hm_rv_fd file descriptor is returned, -1 means see errno |
31 | m4_dnl hm_rv_succfail returns 0 (ok) or -1 (see errno) |
32 | m4_dnl hm_rv_len(<max>) returns length read/written, must be <=max, -1 => errno |
73c4c523 |
33 | m4_dnl hm_rv_fcntl syscall is fcntl, do special processing |
bb7ba677 |
34 | m4_dnl <args> is list of macros for arguments, each followed by hm_na |
bb7ba677 |
35 | m4_dnl hm_arg_nullptr(<type>,<arg>) pointer of type type, must be null |
36 | m4_dnl hm_arg_int(<arg>) signed integer |
37 | m4_dnl hm_arg_fdset_io(<arg>,<max>) fd_set, max bit set is in max |
38 | m4_dnl hm_arg_timeval_in_rel_null(<t>) struct timeval*, pass in, relative, may be null |
39 | m4_dnl hm_arg_must(<type>,<arg>,<val>) must have correct value, or abort test |
40 | m4_dnl hm_arg_socktype(<arg>) SOCK_STREAM or SOCK_DGRAM (an int) |
396a1869 |
41 | m4_dnl hm_arg_addrfam(<arg>) a supported address family |
bb7ba677 |
42 | m4_dnl hm_arg_ign(<type>,<arg>) input parameter ignored |
43 | m4_dnl hm_arg_fd(<arg>) fd |
44 | m4_dnl hm_arg_fcntl_cmd_arg(<ca>,<aa>) syscall is fcntl, do special processing |
45 | m4_dnl hm_arg_addr_in(<arg>,<len>) struct sockaddr*, length given by <len> (an int) |
46 | m4_dnl hm_arg_bytes_in(<objtype>,<objarg>,<lentype>,<lenarg>) |
47 | m4_dnl some data from caller; <objarg> is of type pointer to const <objtype> |
48 | m4_dnl and points to <lenarg> bytes (<lenarg> is of type <lentype>) |
49 | m4_dnl hm_arg_bytes_out(<objtype>,<objarg>,<lentype>,<buflenarg>) |
50 | m4_dnl buffer for data from syscall; <objarg> is of type pointer to const <objtype> |
51 | m4_dnl and points to at least <lenarg> bytes (<lenarg> is of type <lentype>) |
52 | m4_dnl return value from syscall is supposed to be returned length |
53 | m4_dnl hm_arg_addr_out(<arg>,<lenptr>) struct sockaddr*, length io at <lenptr> (an int*) |
