DOC: KeyboardProc() Not Required in DLL for Task Hook

ID: Q102943

The information in this article applies to:

Microsoft C/C++ for MS-DOS, version 7.0
Microsoft Visual C++ for Windows, 16-bit edition, versions 1.0, 1.5

The online help for Microsoft C/C++ version 7.0 and for Visual C++ versions 1.0 and 1.5 all say the following about KeyboardProc():

The KeyboardProc function is a library-defined callback function that the system calls whenever the application calls the GetMessage or PeekMessage function and there is a WM_KEYUP or WM_KEYDOWN keyboard message to process.

Under Windows version 3.1 [using the SetWindowsHookEx() function instead of SetWindowsHook()], it is not necessary for the KeyboardProc() function to be placed in a dynamic-linked library (DLL) if it is being used as a task-specific hook.
