MiniObject.setQdata

void setQdata(glib.types.Quark quark, void * data, glib.types.DestroyNotify destroy)

This sets an opaque, named pointer on a miniobject. The name is specified through a #GQuark (retrieved e.g. via [glib.global.quarkFromStaticString]), and the pointer can be gotten back from the object with [gst.mini_object.MiniObject.getQdata] until the object is disposed. Setting a previously set user data pointer, overrides (frees) the old pointer set, using null as pointer essentially removes the data stored.

destroy may be specified which is called with data as argument when the object is disposed, or the data is being overwritten by a call to [gst.mini_object.MiniObject.setQdata] with the same quark.

Parameters

`quark`	A #GQuark, naming the user data pointer
`data`	An opaque user data pointer
`destroy`	Function to invoke with data as argument, when data needs to be freed
