    Those are in C. I know it says C++, but there is nothing in the code that prohibits you from using them in C programs (C is, roughly, a subset of C++). Also, those pages contain links to the API documentation for the functions EnumProcesses and GetProcessMemoryInfo, which in turn will link you to all the process API functions you need. They will almost certainly all be in C.

    you're right, tanx for your answer
    i find out what is the problem. i copy the msdn's example into the c project but it dosnt work. i asked someone and he told me i should copy psapi.dll (which includes process api functions) into the project folder. but this way did'nt work too.

    please someone tell me how can i fix this problem

    Maybe you should try telling us how it doesn't work. Post your errors and your code!

    i'm using this code Enumerating All Processes

    and the errors are:
    undefined references to 'EnumProcesses@12'
    undefined references to 'EnumProcessModules@16'
    undefined references to 'GetModuleBaseName@16'

    by the way, i'm using code blocks but i try this in visual studio too

    Did you link to the correct library?
    Google implies the correct library is "psapi" for the first "undefined reference".

    Newbie NOTE: A header file is NOT a library and is used in the compiling stage NOT the linking stage.

    note : you want psapi.lib in your linker command, not psapi.dll to get the link to work. the dll is needed at runtime and will already be in the proper location on your system (\windows\system32).

    Kernel32.lib on Windows 7 and Windows Server 2008 R2;
    Psapi.lib if PSAPI_VERSION=1 on Windows 7 and Windows Server 2008 R2;
    Psapi.lib on Windows Server 2008, Windows Vista, Windows Server 2003, and Windows X
