I'm working on implementing a log based file system for a file as a class project. I have a good amount of it working on my 64 bit OS X laptop, but when I try to run the code on the CS department's 32 bit linux machines, I get a seg fault.

I'm using:
ReadProcessMemory(hProcess,(PVOID)(dwEngine_DLL+0x2E15C8+i),&memSnap[i],1,NULL); //Store the memory into a byte array

Hi,
I want to copy an int array to another int array. They use the same define for length so they'll always be of the same length.
What are the pros/cons of the following two alternatives of the size parameter to memcpy()?
memcpy(dst, src, ARRAY_LENGTH*sizeof(int));
or
