NAME¶

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

HEADER FILE¶

Defined in SDL3/SDL_render.h

SYNOPSIS¶

#include "SDL3/SDL.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¶

You may only call this function from the main thread.

AVAILABILITY¶
