pause - wait for signal
#include <unistd.h>
int pause(void);
pause() causes the calling process (or thread) to sleep until a signal is
delivered that either terminates the process or causes the invocation of a
signal-catching function.
pause() returns only when a signal was caught and the signal-catching
function returned. In this case,
pause() returns -1, and
errno
is set to
EINTR.
- EINTR
- a signal was caught and the signal-catching function returned.
