You probably want usleep instead, which takes a microsecond-precision
parameter, and is available to user-land programs.

I'm trying to do a short delay in a user level C program for sending
bytes out to a serial port using IOSleep().
I'm getting _IOSleep symbol not found error when building.
I am including
#include <IOKit/IOKitLib.h> in the program and do not get any
compile errors.
And I have IOKit.framework in the project. It seems like _IOSleep is
in IOKit.h but that does not seem to be in the IOKit.framework.
Now I'm not sure how to resolve the issue.
Which framework should I have in my project?
Should I be using something else for my delay?
This is running on 10.5.6, Xcode 3.1.2, building for i386, and base
SDK Mac OS X 10.4.
Thx for any tips.
