NAMEsgetmask, ssetmask - manipulation of signal mask (obsolete)
DESCRIPTIONThese 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.
RETURN VALUEsgetmask() always successfully returns the signal mask. ssetmask() always succeeds, and returns the previous signal mask.
ERRORSThese system calls always succeed.
CONFORMING TOThese system calls are Linux-specific.
NOTESGlibc 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).
