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

     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
     work).

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

     XResQueryClients fills  a  list  of  clients  of  the  given
     display.  For  each  client  it  returns  in  the XResClient

     structure 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
     failure.

     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
     failure.

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