NAME
pthread_sigmask -- examine and/or change a thread's signal mask
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <signal.h> int pthread_sigmask(int how, const sigset_t * restrict set, sigset_t * restrict oset);
DESCRIPTION
The 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_BLOCK Union of the current mask and set. SIG_UNBLOCK Intersection of the current mask and the complement of set. SIG_SETMASK set. If 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.
RETURN VALUES
If successful, pthread_sigmask() returns 0. Otherwise, an error is returned.
ERRORS
pthread_sigmask() shall fail if: [EINVAL] how is not one of the defined values.
