生成dll库
#include<Windows.h>
//导出函数，可以加载的时候调用
_declspec(dllexport) void msg()
{
MessageBoxA(0, "1", "2", 0);
}
//导出函数，可以加载的时候调用
_declspec(dllexport) int add(int a, int b)
{
return a + b;
}
调用dll库
#include<Windows.h>
#include<stdlib.h>
#include<stdio.h>
typedef void(*procA)();
typedef int (*procB)(int a,int b);
void main()
{
HMODULE hdll = LoadLibrary("DLL.dll"); //加载dll
if (hdll != NULL)
{
procB proc1 = (procB*)GetProcAddress(hdll, "add");
if (proc1 != NULL)
{
printf("%d", proc1(4, 8));
}
FARPROC proc = GetProcAddress(hdll, "msg");
if (proc != NULL)
{
proc();
}
}
return 0;
}
