“APIENTRY_tWinMain”和“WINAPI WinMain”区别 [英] "APIENTRY _tWinMain" and "WINAPI WinMain" difference

问题描述

与这两个函数有什么不同？：

What are the difference from these 2 function?:

int APIENTRY _tWinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPTSTR    lpCmdLine,
                     int       nCmdShow)

int WINAPI WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPTSTR    lpCmdLine,
                     int       nCmdShow)

推荐答案

_tWinMain 只是tchar.h中相应版本 WinMain 的 #define 快捷方式。

_tWinMain is just a #define shortcut in tchar.h to the appropriate version of WinMain.

如果定义 _UNICODE ，则 _tWinMain 展开为 wWinMain 。否则， _tWinMain 与 WinMain 相同。

If _UNICODE is defined, then _tWinMain expands to wWinMain. Otherwise, _tWinMain is the same as WinMain.

相关的宏看起来像这样（实际上有很多其他代码穿插）：

The relevant macro looks something like this (there's actually a lot of other code interspersed):

#ifdef  _UNICODE
#define _tWinMain  wWinMain
#else
#define _tWinMain  WinMain
#endif
