    Windows Memory Allocation :: C++

    Hi.

    C++ offers the new operator to allocate a section of memory via heap.

    C offers the general malloc set of functions to allocate a section of memory via heap.

    Windows offers a series of functions. I would like to know what is the best memory allocation tool to use under windows. Again, I am a C++ programmer.

    I believe Windows has these memory related functions.

    GlobalAlloc()
    GlobaFree()
    HeapAlloc()
    HeapFree()
    LocalAlloc()
    LocalFree ()

    I would like to like under a C++ Windows program, what are the most appropriate memory allocation tool to use? Currently, I use C++ new operator to develop Windows winsock programs. However, I see programmers use GlobalAlloc almost all the time for Windows and Windows network programs. What is the advantage, if any, of GlobalAlloc that C++ new lacks, if any?

    Thanks,
    Kuphryn

    operator new often calls malloc which in turn can call HeapAlloc...

    GlobalAlloc & LocalAlloc are remnants of Win16 and map to HeapAlloc anyway....Dont bother with them

    I prefer to use new (extensible, portable, typesafe ect....), but if I want any API representation, then HeapAlloc

    Okay. Thanks.

    A member posted an article from Microsoft MSDN with a lot of information about memory management in Win32.
