pause - Man Page

Standard C library (libc, -lc)

#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.
