Overview

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.

Function parameters

texture: a texture locked by SDL_LockTexture ().

Thread safety

This function should only be called on the main thread.
