// MODULE: winmain.c
//
// PURPOSE: Calls initialization functions and processes the message loop
//
//
// PLATFORMS: Windows 95, Windows NT
//
// FUNCTIONS:
// WinMain() - calls initialization functions, processes message loop
//
// COMMENTS:
//
//
#include <windows.h> // required for all Windows applications
#include "globals.h" // prototypes specific to this application
//
// FUNCTION: WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
//
// PURPOSE: calls initialization function, processes message loop
//
// PARAMETERS:
//
// hInstance - The handle to the instance of this application that
// is currently being executed.
//
// hPrevInstance - This parameter is always NULL in Win32
// applications.
//
// lpCmdLine - A pointer to a null terminated string specifying the
// command line of the application.
//
// nCmdShow - Specifies how the main window is to be diplayed.
//
// RETURN VALUE:
// If the function terminates before entering the message loop,
// return FALSE.
// Otherwise, return the WPARAM value sent by the WM_QUIT message.
//
//
// COMMENTS:
//
// Windows recognizes this function by name as the initial entry point
// for the program. This function calls the initialization routine
// It then executes a message retrieval and dispatch loop that is the
// top-level control structure for the remainder of execution. The
// loop is terminated when a WM_QUIT message is received, at which
// time this function exits the application instance by returning the
// value passed by PostQuitMessage().
//
// If this function must abort before entering the message loop, it
// returns the conventional value NULL.
//
