NAME
SDL_UnlockTexture - Unlock a texture, uploading the changes to video memory, if needed.
SYNOPSIS
#include <SDL3/SDL_render.h>
void SDL_UnlockTexture(SDL_Texture *texture);
DESCRIPTION
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.
AVAILABILITY
