    Question knowing what functions are in a header file

    hi!

    in visual basic you can open a .bas file and know the functions and know what it does. i open a windows.h file and look for the Sleep() function but i cant find it. I use it all the time....All i see is some wierd stuff....Thanks....

    header files in C++ typcially just show you how to use the function, not how the function is implemented. The implementation business is usually in a cpp file, if you write it, or a library file (which will be in binary or hexadecimal) if it is a commercial header.

    The function bodies are usually stored in compiled OBJ and/or LIB files. You cannot open them.

    To know how to use the functions, look in the *.h files (at least you see the syntax) or in the documentation.

    In a header file usually the definitions are stored. So you won't find functions in header files. You can find prototypes of the function in it. These functions are actually stored in libraries. You should check the documentation of your library to see what's in it and how to use it.
