In traditional embedded programming, we will give a delay function like so:

for(i=0;i<255;i++)
   for(j=0;j<255;j++);

There's more information on how sleep() works here

By the way, busy waiting is not necessarily for amateurs--although it does burn processor that you may want to use for some other purpose. If you are using a time source, you are limited to the granularity of that source. E.G. if you have a 1 ms timer, and want to way 500 uS, you have a problem. If your embedded system can handle the fact that you'll be buzzing in a loop for 500 uSec, that might be acceptable. And even if you have a timer with your desired granularity, you also need to get an interrupt off that timer at the right time...then dispatch ot the interrupt handler...then get to your code. Sometimes a busy loop is the most expedient solution. Sometimes.
