This argument can be NULL if you don't need this information. |- |'''access''' |a pointer filled in with the actual access to the texture (one of the [[SDL_TextureAccess]] values). This argument can be NULL if you don't need this information. |- |'''w''' |a pointer filled in with the width of the texture in pixels. This argument can be NULL if you don't need this information. |- |'''h''' |a pointer filled in with the height of the texture in pixels. This argument can be NULL if you don't need this information. |} == Return Value == Returns 0 on success or a negative error code on failure; call [[SDL_GetError]]() for more information. == Version == This function is available since SDL 2.0.0. == Related Functions == :[[SDL_CreateTexture]] ---- [[CategoryAPI]]
