Hi,

If your timing requirement is not very precise and if you don't mind
wasting processor cycles, you can use the 'clock()' function
effectively to create the delay.
The code would be some thing like...

c1 = c2 = clock();
while ((float)(c2-c1)/CLOCKS_PER_SEC < delaytime) c2 = clock();

'delaytime' is a float and it represents 'seconds' and not 'milliseconds'
