PAUSE(3P) POSIX Programmer's Manual PAUSE(3P)
PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond-
ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
NAME
pause - suspend the thread until a signal is received
SYNOPSIS
#include <unistd.h>
int pause(void);
DESCRIPTION
The pause() function shall suspend the calling thread until delivery of a signal whose action is either to execute a signal-catching func-
tion or to terminate the process.
If the action is to terminate the process, pause() shall not return.
If the action is to execute a signal-catching function, pause() shall return after the signal-catching function returns.
RETURN VALUE
Since pause() suspends thread execution indefinitely unless interrupted by a signal, there is no successful completion return value. A
value of -1 shall be returned and errno set to indicate the error.
ERRORS
The pause() function shall fail if:
EINTR A signal is caught by the calling process and control is returned from the signal-catching function.
The following sections are informative.
EXAMPLES
None.
APPLICATION USAGE
Many common uses of pause() have timing windows. The scenario involves checking a condition related to a signal and, if the signal has not
occurred, calling pause(). When the signal occurs between the check and the call to pause(), the process often blocks indefinitely. The
sigprocmask() and sigsuspend() functions can be used to avoid this type of problem.
RATIONALE
None.
FUTURE DIRECTIONS
None.
