SLEEP(3)SLEEP(3)NAMEsleep - suspend execution for interval
SYNOPSIS
int sleep(unsigned int seconds);
DESCRIPTION
The current process is suspended from execution for the number of
seconds specified by the argument. The actual suspension time may be
up to 1 second less than that requested, because scheduled wakeups
occur at fixed 1-second intervals, and an arbitrary amount longer
because of other activity in the system.
RETURNS
If the sleep function returns because the requested time has elapsed,
the value returned will be zero. If the sleep function returns due to
the delivery of a signal, the value returned is the requested time
minus the time actually slept, in seconds.
ERRORS
[EAGAIN] A resource is temporarily unavailable.
