pause(2)
pause --
suspend process until signal
Synopsis
#include <unistd.h>
int pause(void);
Description
pause suspends the calling process until it receives a signal of any type.
The signal must be one that is not currently set to be ignored.
If the signal causes termination of the process, pause
does not return.
Return values
If the signal is
caught
by the calling process and control is returned from
the signal-catching function
[see
signal(2)],
the calling process
resumes execution from the point of suspension
with a return value of
-1 from pause and errno
set to EINTR.
Errors
In the following conditions,
the calling process resumes from the point of suspension
with errno set to:
EINTR-
A signal was caught by the calling process.
