sprintf(smem_options,"#transcode{vcodec=RV24}:smem{"
     "video-prerender-callback=%lld,"
     "no-time-sync},",(long long int)(intptr_t)(void*)&cbVideoPrerender
);

如何在类中将函数参数传递给sprintf？

sprintf(smem_options,(long long int)(intptr_t)(void*)&cbVideoPrerender
);

我得到的错误信息是：错误C2276：’&’ ：绑定成员函数表达式的非法操作
