//  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. 
//
