Application program memory area

[avaneesh]

Hi friends,

One query. every program is loaded into memory for execution. Considering only those programs loaded in RAM, is there any way to determine where in my RAM my application program is ruuning ? I mean is my program running in STACK, HEAP, CODE SEGMENT, DATA SEGMENT ?

Any help ?

Basically, there's no way to know where in physical RAM your app resides.
However, to answer this:

I mean is my program running in STACK, HEAP, CODE SEGMENT, DATA SEGMENT ?

Your program is running in memory. The code was loaded from the code (.text) segment of your exe, the static data was loaded from the data (.data) segment of your exe. The function locals and return addresses are on the stack and whatever you allocated is on the heap.
Segments in this case are parts of an exe file, not of memory. Stack and Heap are two concepts of memory usage, not areas in memory.

You can use GetModuleHandle to return the memory address of a module. (module meaning the application exe itself, or any .dll's its using)

Most applications start at address 0x400000. You can use ReadProcessMemory and WriteProcessMemory to read/write to the memory.

That's not the address in memory.

Make 5 different apps, load them all and let every one call GetModuleHandle. Very likely all will return 0x400000.

It actually is the address in the process' address space, that is, an address mapped to some physical memory address which you'll never find out.
