NAME

sigpause − atomically release blocked signals and wait for interrupt

SYNOPSIS

sigpause(sigmask)
long 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 0L to indicate that no signals are now 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.
