SLEEP(3) Linux Programmer's Manual SLEEP(3)NAMEsleep - Sleep for the specified number of secondsSYNOPSIS#include <unistd.h> unsigned int sleep(unsigned int seconds);DESCRIPTIONsleep() makes the current process sleep until seconds seconds have elapsed or a signal arrives which is not ignored.RETURN VALUEZero if the requested time has elapsed, or the number of seconds left to sleep.CONFORMING TOPOSIX.1BUGSsleep() may be implemented using SIGALRM; mixing calls to alarm() and sleep() is a bad idea. Using longjmp() from a signal handler or modifying the handling of SIGALRM while sleeping will cause undefined results.SEE ALSOsignal(2), alarm(2)GNU1993-04-07 SLEEP(3)
