usleep(3c)

Standard C Library Functions                                        usleep(3C)



NAME
       usleep - suspend execution for interval in microseconds

SYNOPSIS
       #include <unistd.h>

       int usleep(useconds_t useconds);

DESCRIPTION
       The usleep() function suspends the caller from execution for the number
       of microseconds specified by the useconds argument. The actual  suspen‐
       sion  time  might be less than requested because any caught signal will
       terminate usleep() following execution of that signal's  catching  rou‐
       tine.  The  suspension  time might be longer than requested by an arbi‐
       trary amount because of the scheduling of other activity in the system.


       If the value of useconds is 0, then the call has no effect.


       The use of the usleep() function has no effect on the action or  block‐
       age of any signal. In a multithreaded process, only the invoking thread
       is suspended from execution.

RETURN VALUES
       On completion, usleep() returns 0. There are no error returns.

ERRORS
       No errors are returned.

USAGE
       The usleep()  function  is  included  for  its  historical  usage.  The
       nanosleep(3C) function is preferred over this function.
