sigpause(2)

NAME

     sigpause -- atomically release blocked signals and wait for interrupt


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <signal.h>

     int
     sigpause(int sigmask);


DESCRIPTION

     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


SEE ALSO

     kill(2), sigaction(2), sigblock(2), sigprocmask(2), sigsuspend(2),
     sigvec(2)


STANDARDS

     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'').


HISTORY

     The sigpause() function appeared in 4.2BSD and has been deprecated.
