NAME
SDL_CleanupPropertyCallback - A callback used to free resources when a property is deleted.
HEADER FILE
Defined in SDL3/SDL_properties.h
SYNOPSIS
#include "SDL3/SDL.h"
typedef void (SDLCALL *SDL_CleanupPropertyCallback)(void *userdata, void *value);
DESCRIPTION
This should release any resources associated with value that are no longer needed.
This callback is set per-property. Different properties in the same group can have different cleanup callbacks.
This callback will be called _during_
SDL_SetPointerPropertyWithCleanup
if the function fails for any reason.
FUNCTION PARAMETERS
- userdata
-
an app-defined pointer passed to the callback.
- value
-
the pointer assigned to the property to clean up.
THREAD SAFETY
This callback may fire without any locks held; if this is a concern, the app should provide its own locking.
AVAILABILITY
This datatype is available since SDL 3.2.0.
