sgetmask, ssetmask — manipulation of signal mask
(obsolete)
Synopsis
long
sgetmask(
void);
long
ssetmask(
long
newmask);
DESCRIPTION
These system calls are obsolete. Do not use them; use sigprocmask(2) instead.
sgetmask() returns the
signal mask of the calling process.
ssetmask() sets the signal
mask of the calling process to the value given in newmask. The previous signal
mask is returned.
The signal masks dealt with by these two system calls are
plain bit masks (unlike the sigset_t used by sigprocmask(2)); use
sigmask(3) to create and
inspect these masks.
RETURN VALUE
sgetmask() always
successfully returns the signal mask. ssetmask() always succeeds, and returns the
previous signal mask.
ERRORS
These system calls always succeed.
CONFORMING TO
These system calls are Linux-specific.
NOTES
Glibc does not provide wrappers for these system calls;
use syscall(2).
These system calls are unaware of signal numbers greater
than 31 (i.e., real-time signals).
