sleep
SLEEP(3) Linux Programmer's Manual SLEEP(3)NAME
sleep - Sleep for the specified number of seconds
SYNOPSIS
#include <unistd.h>
unsigned int sleep(unsigned int seconds);
DESCRIPTION
sleep() makes the calling thread sleep until seconds seconds have elapsed or a signal arrives which is not ignored.
RETURN VALUE
Zero if the requested time has elapsed, or the number of seconds left to sleep, if the call was interrupted by a signal handler.
CONFORMING TO
POSIX.1-2001.
BUGS
sleep() may be implemented using SIGALRM; mixing calls to alarm(2) and sleep() is a bad idea.
Using longjmp(3) from a signal handler or modifying the handling of SIGALRM while sleeping will cause undefined results.
SEE ALSO alarm(2), nanosleep(2), signal(2), signal(7)COLOPHON
