    Thumbs up urgent doubt in windows programming, please help me

    The below code when run, assuming necessary header files will give following output?

    Code:
    HANDLE hProcess = CreateProcess(..);
    WaitForSingleObject(hProcess, INFINITE);
    a) wait for I/O
    b) scheduled
    c)finished executed
    d)wait infinite

    I guess it won't wait here....what do you think?

    the logic of the code snippet is all wrong. CreateProcess does not return a HANDLE. it returns a BOOL value indicating success or failure. the handle comes from the process structure you pass to CreateProcess. if CreateProcess is successful, you will be waiting on a handle of some undefined, nonzero value, which is of no relevance to the process you created. if CreateProcess fails, you'll be waiting on the "System Idle Process," which will likely block forever. you may be correct in thinking it won't return, but you also may be wrong, depending on the result of CreateProcess. therefore the behavior of your program here is undefined.

    Er... moderators?

    Four random spammed multiple choice questions obviously from some sort of test with no effort to try to answer the question / justify their answer themselves and couldn't even keep them in the same thread?

    - Compiler warnings are like "Bridge Out Ahead" warnings. DON'T just ignore them.
    - A compiler error is something SO stupid that the compiler genuinely can't carry on with its job. A compiler warning is the compiler saying "Well, that's bloody stupid but if you WANT to ignore me..." and carrying on.
    - The best debugging tool in the world is a bunch of printf()'s for everything important around the bits you think might be wrong.

    it might, or it might not. like I said, the behavior of this program is undefined.
