// 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
#include "resource.h"
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.
//
