NAME

       SDL_CleanupPropertyCallback - A callback used to free resources when a property is deleted.

SYNOPSIS

       #include <SDL3/SDL_properties.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.
