NAME

sigsetmask − set current signal mask

SYNOPSIS

long sigsetmask(mask);
long mask;

HP-UX COMPATIBILITY

Level: HP-UX/STANDARD

Origin: UCB

DESCRIPTION

Sigsetmask 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 (that is, if (mask & (1L << (i-1))) != 0 ). 

It is not possible to mask those signals which cannot be ignored, as documented in signal(2); this restriction is silently imposed by the system.

Sigblock(2) can be used to add elements to the set of blocked signals.

RETURN VALUE

The previous set of masked signals is returned.
