Hi Prakash,

If you "man usleep" you'll notice that it specifies that "actual suspension
may be longer than the amount of time specified".

> Please let me know if there is a way of achieving a sleep for a SPECIFIC
precision value in milliseconds range...

Depends on the facilities of your operating system and platform, not on the
capabilities of GCC.

You could try a busy loop, or a vertical blanking interrupt, or a specific
OS call giving more exacting sleep control.

Sincerely,
