windows.h is a Windows-specific header file for the C/C++ programming language which contains declarations for all of the functions in the Windows API, all the common macros used by Windows programmers, and all the data types used by the various functions and subsystems.
But i have a question regarding windows. Since every window class has a windows procedure that is associated with all windows of the same class, does that windows procedure have a name? or does the name of the procedure matter at all?
The name of the proceedure does not matter; only its address.
When a window class is registered using RegisterClassEx() the lpfnWndProc member of the WNDCLASSEX structure passed to this function is set to point at the proceedure for the new window class.
