軟件測試工具LoadRunner調用一個(gè)簡(jiǎn)單Dll例子

有關(guān)DLL的編寫(xiě)代碼，在VC里面新建一個(gè)Win32 Dynamic-Link Library類(lèi)型的空項目，源碼如下：
// DllProject.cpp : Defines the entry point for the DLL application.
//
#include <windows.h>
#define   DLLEXPORT extern "C" _declspec(dllexport)

DLLEXPORT int add(int a, int b);
DLLEXPORT int sub(int a, int b);

BOOL APIENTRY DllMain( HANDLE hModule,
                        DWORD   ul_reason_for_call,
                        LPVOID lpReserved
                      )
...{
    switch( ul_reason_for_call )
    ...{
    case DLL_PROCESS_ATTACH:
        break;
    case DLL_THREAD_ATTACH:
        break;
    case DLL_THREAD_DETACH:
        break;
    case DLL_PROCESS_DETACH:
        break;
    default:
        break;
     }    
    return TRUE;
}

int add(int a ,int b)
...{
    return a+b;
}

int sub(int a ,int b)
...{
    return a-b;
}
編譯生成dll文件，然后在Loadrunner中調用，代碼如下：
Action()
...{
     lr_load_dll("C:\tmp\DllProject\Debug\DllProject.dll");
     lr_output_message(" %d",add(5,6));
     lr_output_message(" %d",sub(5,6));
    return 0;
}
