关于WinMain的问题

[babybear315]

最近在学windows编程，从api开始，
老书上写的是int PASCAL WinMain()
新书上是 int WinAPI WinMain()
请问这两个有什么区别，还有我在编译程序的时候声明函数
long FAR PASCAL_export WinPor()时就编译不过
而改为 long CALLBACK 就可以，为什么呢？

int PASCAL WinMain()中PASCAL调用是老的调用方式，在WIN32中已经废弃了，改为WinAPI了。
你的WinPor（）是不是回调函数啊，如果是就不能long FAR PASCAL_export WinPor()，一定要改为long CALLBACK WinPor()或者long CALLBACK _export WinPor()

用WINAPI格式，简单书写如下

#include "stdafx.h"
#include <windows.h>
HWND hwnd;

LRESULT CALLBACK WndProc(HWND,UINT,WPARAM,LPARAM);
void CALLBACK MyTimerProc( UINT uID, UINT uMsg, DWORD dwUser, DWORD dw1, DWORD dw2 );
void
CALLBACK MyTimerProc( UINT uID, UINT uMsg, DWORD dwUser, DWORD dw1, DWORD dw2 )
{
//::MessageBox( hwnd, "NULL", "NULL", MB_OK );
}

int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInst, LPSTR lpszCmdLine, int nCmdShow )
{
MSG Msg;
WNDCLASS wndclass;
char lpszClassName[]="Class";
char lpszTitle[]="窗口示例";

wndclass.style=0;
wndclass.lpfnWndProc=WndProc;
wndclass.cbClsExtra=0;
wndclass.cbWndExtra=0;
wndclass.hInstance=hInstance;
wndclass.hIcon=LoadIcon(NULL,IDI_APPLICATION);
wndclass.hCursor=LoadCursor(NULL,IDC_ARROW);
wndclass.hbrBackground = ( HBRUSH )GetStockObject( WHITE_BRUSH );
wndclass.lpszMenuName=NULL;
wndclass.lpszClassName=lpszClassName;


if(!RegisterClass(&wndclass))
{
MessageBeep(0);
return FALSE;
}
hwnd=CreateWindow(lpszClassName,
lpszTitle,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL);
::SetTimer( hwnd, 8888, 1000, ( TIMERPROC )MyTimerProc );
ShowWindow( hwnd,nCmdShow);
UpdateWindow( hwnd );
while(GetMessage(&Msg,NULL,0,0))
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}
LRESULT CALLBACK WndProc( HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch(message)
{
case WM_DESTROY:
PostQuitMessage(0);
break;
}
return DefWindowProc(hwnd,message,wParam,lParam);
}
