NAME
sleep, alarm - delay, ask for delayed note
SYNOPSIS
#include <u.h> #include <libc.h> int sleep(long millisecs) long alarm(unsigned long millisecs)
DESCRIPTION
Sleep suspends the current process for the number of milliseconds specified by the argument. The actual suspension time may be a little more or less than the requested time. If millisecs is 0, the process gives up the CPU if another process is waiting to run, returning imme- diately if not. Sleep returns -1 if interrupted, 0 otherwise. Alarm causes an alarm note (see notify(2)) to be sent to the invoking process after the number of milliseconds given by the argument. Suc- cessive calls to alarm reset the alarm clock. A zero argument clears the alarm. The return value is the amount of time previously remain- ing in the alarm clock.
