#include <unistd.h>

int pause(void);

The pause library function causes the invoking process (or thread) to sleep until a signal is received that either terminates it or causes it to call a signal-catching function.

The pause function only returns 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.
