PAUSE(3) BSD Programmer's Manual PAUSE(3)
pause - stop until signal
#include <unistd.h> int pause(void);
Pause is made obsolete by sigsuspend(2). The pause() function forces a process to pause until a signal is received from either the kill(2) function or an interval timer (see setitimer(2)). Upon termination of a signal handler started during a pause(), the pause() call will return.
Always returns -1.
The pause() function may set the global variable errno to the following error: [EINTR] The call was interrupted.
kill(2), select(2), setitimer(2), sigsuspend(2)
A pause() system call appeared in Version 6 AT&T UNIX. MirOS BSD #10-current June 4, 1993 1
