SDL_CleanupPropertyCallback.3type - Man Page

#include <SDL3/SDL_properties.h>

typedef void (SDLCALL *SDL_CleanupPropertyCallback)(void *userdata, void *value);

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.

userdata

an app-defined pointer passed to the callback.

value

the pointer assigned to the property to clean up.

This callback may fire without any locks held; if this is a concern, the app should provide its own locking.

This datatype is available since SDL 3.2.0.
