     X-Resource is an extension that allows a client to query the
     X server about its usage of various resources. It should not
     be mixed with the X resource database access functions.

     XResQueryExtension returns True if the XRes extension is
     available on the given display. A client must call
     XResQueryExtension before calling any other XRes function in
     order to negotiate a compatible protocol version; otherwise
     the client will get undefined behavior (XRes may or may not

     XResQueryVersion returns True if the request succeeded; the
     values of the major and minor protocol versions supported by
     the server are returned in major_versionp and minor_versionp

     XResQueryClients fills a list of clients of the given
     display. For each client it returns in the XResClient struc-
     ture a mask and a base value of the resources used by these
     clients. Returns True on success or False on failure.

     XResQueryClientResources fills a list of XResType struc-
     tures, indicating for each resource type allocated by the
     client its name (as an Atom) and the number of resources of
     this type allocated. Returns True on success or False on

     XresQueryClientPixmapBytes gives, for resources of type PIX-
     MAP the total number of bytes allocated in the X server by
     the given client. Returns True on success or False on


     XResQueryClientResources and XResQueryClientPixmapBytes will
     return BadValue if passed an illegal client identifier.
