VS2010中lib与dll文件的生成与使用方法

class __declspec(dllexport) NB （类的头文件中只需修改此处即可）
{
public：
private：
}

#include <Windows.h>     // 包含 HINSTANCE
#include <iostream>
using namespace std;
 
int main()
{
HINSTANCE his = LoadLibraryA("to_test1.dll");//用于加载dll
 
typedef float(*Add)(float a,float b);
Add add1 = (Add)GetProcAddress(his,"add");//GetProcAddress()用于获得函数地址 
 
typedef float(*Min)(float a,float b);
Min add2 = (Min)GetProcAddress(his,"MIN");
cout<<add1(2,3)<<endl;
cout<<add2(2,3)<<endl;
 
FreeLibrary(his);//释放dll
return 0;
}

#include"func_add_min.h"
int main()
{
cout<<add(1,2)<<endl;
cout<<MIN(1,2)<<endl;
return 0;
}

class __declspec(dllexport) NB 
{
public：
private：
}

#include "testDetec.h"

_declspec(dllexport) int testDetect(short* refPcm, int refLen, int refSamprate, int refChannel, short* micPcm, int micLen, int micSamprate, int micChannel){

return resulut;
}

#ifndef _testDetect_H_
#define _testDetect_H_
_declspec(dllexport) int testDetect(short* refPcm, int refLen, int refSamprate, int refChannel, short* micPcm, int micLen, int micSamprate, int micChannel);

#endif
