SLEEP(3) Linux Programmer's Manual SLEEP(3)
NAME
sleep - Sleep for the specified number of seconds
SYNOPSIS
#include<unistd.h>
unsignedintsleep(unsignedint seconds);
DESCRIPTION
sleep() makes the current process sleep until seconds sec
onds have elapsed or a signal arrives which is not
ignored.
RETURNVALUE
Zero if the requested time has elapsed, or the number of
seconds left to sleep.
CONFORMINGTO
POSIX.1
BUGS
sleep() 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.
SEEALSO
signal(2), alarm(2)

Armando Nava: La diferencia entre el sleep y lo tuyo, es q lo tuyo usa la maquina, o sea, sus recursos, pero el sleep() no. Igualmente creo q con las maquinas de hoy en dia, hacer un for hasta 10000 dudo q tarde mucho.
