int APIENTRY WinMain与int WiINAPI WinMain 及int CALLBACK WinMain是一样的 今天写线程函数时,发现msdn中对ThreadProc的定义有要求:DWORD WINAPI ThreadProc(LPVOID lpParameter); 不解为什么要用WINAPI宏定义,查了后发现下面的定义。于是乎需要区别__stdcall和__cdecl两者的区别; #define CALLBACK __stdcall #define...

WinMain是入口，声明是 int APIENTRY WinMain(HINSTANCE hInst, HINSTANCE hPrev, LPSTR szCmd, INT nShow);注意那个LPSTR，它是char 我想你大概听说过什么叫“宽字符”吧？如果是宽字符怎么办呢，有这样一个声明：int APIENTRY wWinMain(HINSTANCE hInst, HINSTANCE hPrev, LPWSTR szCmd, INT nShow);...
int WINAPI WinMain时，系统就是调用main函数处理的。但有些古老的编译环境（比如c的一般编译环境工具）不提供的，所以需要先自己定义一个main函数，与其他函数定义是一样的。WINAPI 表示WindowsAPI函数调用约定，在SDK中定义 #define WINAPI __stdcall 也就是说定义了WINAPI 的函数采用__stdcall调用约定...
