将SDL_Surface"连接"到shared_ptr

Question

我想知道如何将SDL_Surface*与shared_ptr连接？在删除之前我
需要打电话.如何在shared_ptr中"修改删除过程"？SDL_FreeSurface(SDL_Surface*)SDL_Surface

Answer 1

只需将SDL_FreeSurface传递给构造函数:

std::shared_ptr<SDL_Surface> shared_surf(SDL_LoadBMP("foo.bmp"), SDL_FreeSurface);

请确保您不使用SDL_SetVideoMode或返回的指针执行此操作SDL_GetVideoSurface.

@ user1511417:根据[文档](http://www.libsdl.org/docs/html/sdlsetvideomode.html).*"返回的表面由SDL_Quit()释放,并且不应被调用者释放."* (3认同)
