###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_QueryTexture Query the attributes of a texture. ## Header File Defined in [SDL_render.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_render.h) ## Syntax ```c int SDL_QueryTexture(SDL_Texture * texture, Uint32 * format, int *access, int *w, int *h); ``` ## Function Parameters | | | | | ---------------------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | [SDL_Texture](SDL_Texture) * | **texture** | the texture to query. | | Uint32 * | **format** | a pointer filled in with the raw format of the texture; the actual format may differ, but pixel transfers will use this format (one of the [SDL_PixelFormatEnum](SDL_PixelFormatEnum) values). This argument can be NULL if you don't need this information. | | int * | **access** | a pointer filled in with the actual access to the texture (one of the [SDL_TextureAccess](SDL_TextureAccess) values). This argument can be NULL if you don't need this information. | | int * | **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. | | int * | **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 (int) Returns 0 on success or a negative error code on failure; call [SDL_GetError](SDL_GetError)() for more information. ## Version This function is available since SDL 2.0.0. ## See Also - [SDL_CreateTexture](SDL_CreateTexture) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryRender](CategoryRender)
