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 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 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 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
True on success or
False on failure.
XResQueryClientPixmapBytes gives, for resources of type
PIXMAP 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.
