NAME

sleep - delay

SYNOPSIS

include "sys.m";
sys := load Sys Sys->PATH;

sleep:	fn(period: int): int;

DESCRIPTION

Sleep suspends the current thread for period milliseconds. The actual suspension time may be a little more or less than the requested time. If period is 0, the process gives up the CPU if another process is waiting to run, returning immediately if not.

Sleep normally returns 0. In hosted Inferno it may return -1 to indicate that it was not possible to sleep (eg if no more threads are available).
