title: Where is msleep declared?
body: <p>The source from <a href="http://www.iphonedevsdk.com/forum/iphone-sdk-development/19607-there-any-simple-c-timer-around.html#post236498" rel="nofollow noreferrer">here</a> says that it is supposed to work on the iPhone.  I have worked with it, but I get 2 errors, saying that msleep() is undeclared.  I have tried to include unistd.h, time.h, and numerous others.  How can I get this to work?  Thanks.</p>
