sorry for that.

I copied mutex and semaphore to explain u.

I thought of giving link.

If u want to explain clearly i will explain in my words.

The first thread was not copied.

check my program carefully and compare with which u have given the link.

Why i am telling confidently because i have developed it and i am working on supercomputer
namely Flosolver. This super computer is the India's first parallel supercomputer.

If u still believe i am ready to remove this thread.
