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