MiniObject.take

Modifies a pointer to point to a new mini-object. The modification is done atomically. This version is similar to [gst.mini_object.MiniObject.replace] except that it does not increase the refcount of newdata and thus takes ownership of newdata.

Either newdata and the value pointed to by olddata may be null.

Parameters

olddatapointer to a pointer to a mini-object to be replaced
newdatapointer to new mini-object

Returns

true if newdata was different from olddata
