sleep — Sleep for the specified number of seconds
#include <unistd.h>
unsigned int sleep( |
unsigned int | seconds); |
sleep() makes the calling
process sleep until seconds seconds have elapsed or
a signal arrives which is not ignored.
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.
