XRes - X-Resource extension client library
SYNOPSIS
#include <X11/extension/XRes.h>
typedef struct {
XID resource_base;
XID resource_mask;
} XResClient;
typedef struct {
Atom resource_type;
unsigned int count;
} XResType;
Bool XResQueryExtension(Display *dpy, int *event_basep, int
*error_basep);
Status XResQueryVersion(Display *dpy, int *major_versionp,
int *minor_versionp);
Status XResQueryClients(Display *dpy, int *num_clients,
XResClient **clients);
Status XResQueryClientResources(Display *dpy, XID xid, int
*num_types, XResType **types);
Status XResQueryClientPixmapBytes(Display *dpy, XID xid,
unsigned long *bytes);
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 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
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_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
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.
