MiniObject.take

bool take(gst.mini_object.MiniObject olddata, gst.mini_object.MiniObject newdata)

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

`olddata`	pointer to a pointer to a mini-object to be replaced
`newdata`	pointer to new mini-object

Returns

true if newdata was different from olddata
