bool sdlGetTextureAlphaMod(
  1. Pointer<SdlTexture> texture,
  2. Pointer<Uint8> alpha
)

Get the additional alpha value multiplied into render copy operations.

\param texture the texture to query. \param alpha a pointer filled in with the current alpha value. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.1.3.
