C++ ACE 动态加载链接库

添加头文件

#include <ace/DLL.h>
#include <ace/DLL_Manager.h>

定义函数接口

typedef long (*PFN_TEST)(const char* szName);
PFN_TEST        g_pfnTest = NULL;

加载动态库(dll/so)

    ACE_TCHAR szDName[] = {  };
    strncpy(szDName, D_NAME, );    

    ACE_DLL m_hD;
    int nRet = m_hD.open(szDName);
    if(nRet != )
    {
        cout << "ERROR." << endl;
        m_hD.close();
        return nRet;
    }

调用动态库函数

g_pfnTest = (PFN_TEST)m_hD.symbol("Test");

    if(g_pfnTest != NULL)
    {
        g_pfnTest ("wjshan0808");
    }
