- // MODULE: init.c
- //
- // PURPOSE: Performs application and instance specific initialization.
- //
- // FUNCTIONS:
- // InitApplication() - Initializes window data and registers window.
- //
- // COMMENTS:
- //
- #include <windows.h> // required for all Windows applications
- #include "globals.h" // prototypes specific to this application
- HINSTANCE hInst; // current instance
- char szAppName[9]; // The name of this application
- char szTitle[40]; // The title bar text
- //
- // FUNCTION: InitApplication(HINSTANCE, int)
- //
- // PURPOSE: Initializes window data and registers window class.
- //
- // PARAMETERS:
- // hInstance - The handle to the instance of this application that
- // is currently being executed.
- // nCmdShow - Specifies how the main window is to be displayed.
- //
- // RETURN VALUE:
- // TRUE - Success
- // FALSE - Initialization failed
- //
- // COMMENTS:
- //
- // This function is called at application initialization time. It
- // performs initialization tasks for the current application instance.
- // Unlike Win16, in Win32, each instance of an application must register
- // window classes.
- //
- // In this function, we initialize a window class by filling out a data
- // structure of type WNDCLASS and calling the Windows RegisterClass()
- // function. Then we create the main window and show it.
- //
- //

- // Fill in window class structure with parameters that describe the
- // main window.
