Shared memory implementation using thread

Hi

I am looking for C program source code. Could you please help me in finding the source code required mentioned below.


Task that I need to complete:

Write a program to create multiple threads (one master thread and rest worker threads) and using the threads write into and read from shared memory

Restrictions:

Only one thread should be able to read at any instant of time into shared memory region.

Only one thread should be able to write at any instant of time into shared memory region.

Worker threads should inform the master thread after every read and write operation.

Master thread inform the worker thread (which is waiting to acquire shared memory region) that read or write operation is successful and it can acquire the memory for either reading and writing operations.


Please send me the code for the same

Do your own homework.

Of course we won't sent you the whole code for obvious reasons. But we can give you some clues. First of all, it is for Windows or Linux?

If you really find it difficult at least give us some psedo-code and we can help with the specific functions and/or details.

It's for AIX and I am new to this OS. Though I have written two separate functions but unable to compile it. I have created an structure and two threads one for reading and another for writing. But nothing seems to be working fine for me.

post your code and somebody will probably find the problem :)

Well, posting the code and the compiler errors would be a start...
