SDL_UnlockTexture - Unlock a texture, uploading the changes to video memory, if needed.

       This function is available since SDL 3.2.0.

Warning:  Please  note  that  SDL_LockTexture()  is  intended to be write-only; it will not guarantee the
       previous contents of the texture will be provided. You must fully initialize any area of a  texture  that
       you lock before unlocking it, as the pixels might otherwise be uninitialized memory.

       Which  is to say: locking and immediately unlocking a texture can result in corrupted textures, depending
       on the renderer in use.
