NAME

sigsetmask − set current signal mask

SYNTAX

sigsetmask(mask);
int mask;

DESCRIPTION

The sigsetmask system call sets the current signal mask (those signals which are blocked from delivery).  Signal i is blocked if the i-th bit in mask is a 1. 

The system quietly disallows SIGKILL, SIGSTOP, or SIGCONT to be blocked. 

The previous set of masked signals is returned.
