Re: DELAY
a delay of micro second is not possible using c++ libraries directly, you have to write s/w for generating interrupt
each operation say addition takes 1(divided by) speed of your computer (say 1.G Hz)
then the operation is completed in 1 nano second... so extend the concept to generate a micro second delay, you can achieve that.. but the program should be at lower level like assembly to generate accurate delays and that program is machine dependent (coz u r writing considering you processor speed)
This is one of the idea... may be a better might be there...
like in java (not in c++) we can delay a thread in nano seconds its a static funtion
delay(milliseconds, nanoseconds)
It is sure that its not impossible.
