Read memory

Hi.
I am trying to make a cheat/anticheat program for old games.

How can you read used memory/RAM? Is it a C++ libary for it? Or do I have to learn assembler, and some hardware?
If so, exactly what do i have to learn of assembly and hardware?

Well you have to say which OS/Compiler you're using.

every time you use malloc(), new, read from a file, read from serial ports, and a whole holst of other functions, the program is reading and using memory in either RAM or on disk. So you will have to be just a tad more specific about your question.

oh, sorry.
I am using Windows XP, and i am using the DevC++ compiler.
I want to make a function like this:

Code:

readMem() {
byte memory[100000];
int Start=0;
int End=GetLastMemory();
while(Start < End) {
bytememory[start]=ReadMemoryCell[start];
start++;
}
}

Or in words, a way to read ALL the memorycells( on the RAM) on the computer, at all times.

That's not so easy. XP won't let you alwais read the memory of another process. check out ReadProcessMemory
