I'm looking for the header file of shm.h , although i've seen some on the web but when i use it the prototype methods are not implemented.... where can i download the full shm.h?

That is a *nix file -- if you are compiling for MS-Windows of some other os then you can't use it.

Well is there a Windows Version? I've seen a window version but the prototype methods are not implemented.

You need to go digging through MSDN to find the equivalent (or at least work-alike) API for the platform you're using.
