sgetmask, ssetmask — manipulation of signal mask (obsolete)
long sgetmask( |
void); |
long ssetmask( |
long newmask); |
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.
sgetmask() always
successfully returns the signal mask. ssetmask() always succeeds, and returns the
previous signal mask.
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).
It is not possible to block SIGSTOP or SIGKILL.
