NAME

       pause - wait for signal

LIBRARY

SYNOPSIS

       #include <unistd.h>

DESCRIPTION

       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.

RETURN VALUE

       catching function returned.  In this case, pause() returns -1,
       and errno is set to EINTR.

ERRORS

              returned.
