SIGPAUSE(2) MidnightBSD System Calls Manual SIGPAUSE(2)
sigpause — atomically release blocked signals and wait for interrupt
Standard C Library (libc, −lc)
This interface is made obsolete by sigsuspend(2).
The sigpause() function 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. The sigmask argument is usually 0 to indicate that no signals are to be blocked. The sigpause() function always terminates by being interrupted, returning -1 with errno set to EINTR
kill(2), sigaction(2), sigblock(2), sigprocmask(2), sigsuspend(2), sigvec(2)
The sigpause() function is implemented for compatibility with historic 4.3BSD applications. An incompatible interface by the same name, which used a single signal number rather than a mask, was present in AT&T System V UNIX, and was copied from there into the X/Open System Interfaces (XSI) option of IEEE Std 1003.1-2001 (‘‘POSIX.1’’).
The sigpause() function appeared in 4.2BSD and has been deprecated.
