VC6中调用DLL动态库

VC6中调用DLL动态库：

使用前要先声明函数：

typedef int (WINAPI * PFN_CONNECT)(char * strHost, char * strUser,char * strPassword, char * strDb);

typedef int (WINAPI * PFN_GETDATA)(char *str_query,struct process_data *head);

函数中调用部份：

    HMODULE  hDLL;
    PFN_CONNECT pFunc_connect = NULL;
    PFN_GETDATA pFunc_getdata = NULL;
    hDLL = LoadLibrary("MonitorTest.dll");
    pFunc_connect = (PFN_CONNECT)GetProcAddress(hDLL,"init_mysql_connection");
    pFunc_getdata = (PFN_GETDATA)GetProcAddress(hDLL,"get_mysql_full_processlist_data");
    int res=0;
    res =(int) pFunc_connect("localhost","root","111111","mysql");
    res =(int) pFunc_getdata("show full processlist;",&struct_out);

 　 ……

　FreeLibrary(hDLL);
