Constraint is Referenced or not?

[highend3djojan-]

How can v find out whether a constraint is a reference or not? Any MEL way?

[joojaa]

You can querry the reference status of ANY node as follows:

referenceQuery -isNodeReferenced nameOfNode

Ok. thnx again, Jooja. One more..
Suppose v r referencing all characters from another scene in order to animate it here. This scene also contains non-referenced objects. HOW can v find the original PATH of the referenced scene file (i.e; 'Unresolved name' in Reference Editor) using MEL? prior to this, v do not knw whether thr is a referenced thing or not, suppose. Need to REMOVE REFERENCE also.

[joojaa]

thet would be the -unresolvedName flag then

[highend3djojan-]

but for that v have to input some string values for flags, rt? How do v knw it?! Can u write a simple example?
Wat i ONLY need is all the unresolved names (or the fullpaths) of references. for e.g; if the scene contains 2 characters and 1 bg, there may be 3 unresolved names (paths to 3 different scenes), like tht.
