pthread_sigmask(int
how, const sigset_t *
restrict set, sigset_t *
restrict oset);
pthread_sigmask() function examines and/or changes
the calling thread's signal mask.
If set is not NULL,
it specifies a set of signals to be modified, and how
specifies what to set the signal mask to:
SIG_BLOCKSIG_UNBLOCKSIG_SETMASKIf oset is not NULL,
the previous signal mask is stored in the location pointed to by
oset.
SIGKILL and
SIGSTOP cannot be blocked, and will be silently
ignored if included in the signal mask.
pthread_sigmask() returns 0. Otherwise,
an error is returned.
pthread_sigmask() shall fail if:
