NAME

sleep, usleep - suspend execution for interval

SYNOPSIS

#include <unistd.h>

unsigned sleep(unsigned seconds);

void usleep(unsigned long usec); // should be of type unsigned long

DESCRIPTION

The current process is supended from execution for the number of seconds (sleep) or microseconds (usleep) specified by the argument. Sleep returns early if a signal is caught; after the signal handler has returned, sleep will return the "unslept" amount. If no signal was caught, and after the full amount of of time (and possibly somewhat longer) has passed, execution is resumed.

NOTES

On UN*X, usleep is of type unsigned int. Under TOS or MiNT before 0.95, these routines do a busy wait until enough time has passed.
