SYNOPSIS

9       #include <unistd.h>
10
11       int pause(void);
12

DESCRIPTION

14       The pause() library function causes the invoking process (or thread) to
15       sleep until a signal is received that either terminates it or causes it
16       to call a signal-catching function.
17

RETURN VALUE

19       The pause() function only returns when a signal was caught and the sig‐
20       nal-catching function returned. In this case pause()  returns  -1,  and
21       errno is set to EINTR.
22

ERRORS

24       EINTR  a signal was caught and the signal-catching function returned.
