NAME
sigpause —
atomically release blocked signals and
wait for interrupt
SYNOPSIS
#include
<signal.h>
int
sigpause(int
sigmask);
DESCRIPTION
This interface is made obsolete by sigsuspend(2).Sigpause()
assigns sigmask to the set of masked signals and then
waits for a signal to arrive; on return the set of masked signals is
restored. Sigmask is usually 0 to indicate that no
signals are to be blocked. Sigpause() always
terminates by being interrupted, returning -1 with
errno set to EINTR
SEE ALSO
sigsuspend(2), kill(2), sigaction(2), sigprocmask(2), sigblock(2), sigvec(2)
HISTORY
The sigpause function call appeared in
4.2BSD and has been deprecated.
