Thread Prog in C language (OS independent)

Why are you using shared memory; are you sharing memory with another application (which is what it's for) or are you assuming that multiple threads that need to share the same memory need to use shared memory (they don't)?

I'll go beyond this(later in the future this will be implemented on multiple process, but right now I am developing and testing it using threads).

Now I am able to create mutiple threads and a single shared memory.

At this point of time I am looking for some help in reading from and writing into one block of shared memory (I need to divide the shared memory into multiple blocks).

my next step is to perform read/write operation on multiple blocks of single shared memory segment.

And the rest of the list will go on in the future post....

Can you provide some clue about proceeding forward... I have already sent a detailed message in my previous post.
