Yes i did this in my header file now.
but using a #if Unix, as i need to define unix in my program.

120 bytes. Why would it give memory corruption, knowing it's just a pointer
to an existing array of 120 bytes? I only give it an address where it needs
to put the small string. 

What's wrong with this, and yes i don't want it to check how long the
string is, it just must put the string at that address , that's it!
