sigpause2

Usage

Library

Standard C Library (libc, -lc)

Overview

This interface is made obsolete by sigsuspend(2).

Sigpause() assigns sig to the set of masked signals and then waits for a signal to arrive; on return the set of masked signals is restored. Sig is usually 0, indicating that no signals are to be blocked. Sigpause() always terminates by being interrupted, returning -1 with errno set to EINTR.

Compatibility

sigpause() now takes a signal value and not a mask. This often appears as a hang in sigpause$UNIX2003 or with sigpause() returning with errno set to EINVAL. Use sigsuspend() with signal masks.
