c语言 - 使用winmain和简单代码编译错误，"Previous decleration of WinMain"

Question

#include <stdio.h> 
#include <windows.h>
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
return(0);
}

我是C的新手。当我尝试编译时，上面的代码返回以下错误：

main.c:3:5: error: conflicting types for 'WinMain'
int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
^~~~~~~
In file included from c:mingwincludewindows.h:44:0,
from main.c:2:
c:mingwincludewinbase.h:1263:14: note: previous declaration of 'WinMain' was here
int APIENTRY WinMain (HINSTANCE, HINSTANCE, LPSTR, int);

Answer 1

您应该使函数定义与库的声明相匹配。你有

int WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)

这需要

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)

缺少APIENTRY。
