  .SH DESCRIPTION
  .B 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.
  .PP
  .B XResQueryExtension
  returns
  .B True
  if the 
  .I XRes
  extension is available on the given display.
  A client must call 
  .B 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).
  .PP
  .B XResQueryVersion
  returns
  .B True
  if the request succeeded; the values of the major and minor protocol
  versions supported by the server are returned in 
  .I major_versionp 
  and 
  .I minor_versionp .
  .PP
  .PP
  .B XResQueryClients 
  fills a list of clients of the given display. For each client it
  returns in the 
  .I XResClient
  structure a mask and a base value of the resources used by these
  clients. 
  Returns 
  .B True
  on success or 
  .B False
  on failure. 
  .PP
  .B XResQueryClientResources
  fills a list of 
  XResType
  structures, indicating for each resource type allocated by the client its
  name (as an Atom) and the number of resources of this type allocated. 
  Returns 
  .B True
  on success or 
  .B False
  on failure. 
  .PP
  .B XresQueryClientPixmapBytes
  gives, for resources of type 
  .I PIXMAP
  the total number of bytes allocated in the X server by the given
  client. 
  Returns 
  .B True
  on success or 
  .B False
  on failure. 
  .SH "ERRORS"
  .B XResQueryClientResources
  and
  .B XResQueryClientPixmapBytes
  will return 
  .I BadValue
  if passed an illegal client identifier.
