use sleep() to sleep for 'seconds'<br />
and usleep() to sleep for &quot;micro seconds&quot;<br />
the delay that sleep gives is quite noticable.<br />
more than 3-4 seconds is rather irritating.

What do I need to include for usleep()? &lt;time.h&gt; does not seem to have it.

Okay, I've got a weirdness w/ my Linux system then. Whenever I request the time in milliseconds or smaller, it give me 0. This might be because the machine I am trying this on is a P133 w/ Red Hat 5.2. I'll accept the usleep include file as the answer, but if anyone has any suggestions, please tell me. Thank you.

Hi,<br />
<br />
I was wondering if there are any delay or sleep function under linux. I need delays of around several milliseconds. I have tried nanosleep, but that does not seem to work very well and does not give pauses for the desired amounts of time. Whenever I tell it to pause for a few seconds it works more or less, but when I tell it to pause for a large amount on nanoseconds it does not pause at all. Are there any alternatives?

Delay Function

Kernel programming for Linux operating systems can be done with many different languages; C, C++, Python, Perl and Java, which are some of the most common languages used.There are also many different varieties of Linux, such as Ubuntu, Fedora and OpenSUSE.
