how to write delay code in c language.

[Banfa]

to perform an efficient delay you need to use a non standard function provided by the operating system for example sleep(...) in Linux or Sleep(...) in Windows.

There is no standard way of efficiently delaying without using processor cycles.

[donbock]

You need a nonstandard high-resolution elapsed-time function even if your delay function is inefficent and uses processor cycles. Either way, you are dependent on nonstandard OS-specific functions. Therefore, a delay function is inherently nonportable.
