// MODULE: init.c
//
// PURPOSE: Performs application and instance specific initialization.
//
// FUNCTIONS:
// InitApplication() - Initializes window data and registers window.
// InitInstance() - Saves instance handle and creates main window.
//
// COMMENTS:
//
#include <windows.h> // required for all Windows applications
#ifdef WIN16
#include "win16ext.h" // required only for win16 applications
#endif
#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)
//
// PURPOSE: Initializes window data and registers window class.
//
// PARAMETERS:
// hInstance - The handle to the instance of this application that
// is currently being executed.
//
// RETURN VALUE:
// TRUE - Success
// FALSE - Initialization failed
//
// COMMENTS:
//
// This function is called at initialization time only if no other
// instances of the application are running. This function performs
// initialization tasks that can be done once for any number of running
// instances.
//
// In this case, we initialize a window class by filling out a data
// structure of type WNDCLASS and calling the Windows RegisterClass()
// function. Since all instances of this application use the same
// window class, we only need to do this when the first instance is
// initialized.

//
// COMMENTS:
// This function is called at initialization time for every instance of
// this application. This function performs initialization tasks that
// cannot be shared by multiple instances.
//
// In this case, we save the instance handle in a static variable and
// create and display the main program window.
