>Description:
man sigismember indicates:
RETURN VALUES
The sigismember() function returns 1 if the signal is a member of the
set, 0 otherwise. The other functions return 0.
ERRORS
Currently no errors are detected.
but implementation contains:
if (signo <= 0 || signo > _SIG_MAXSIG) {
errno = EINVAL;
return (-1);
}
>How-To-Repeat:
>Fix:
Documentation and implementation should be made consistent.
It appears that the FreeBSD behaviour is consistent with what
is done on most other UNIX platforms, with the notable exception
of MacOS X, so the correct course of action is probably to fix
the man page (but we should first check with relevant standards
that this is indeed conformant).
