NAME
XRes - X-Resource extension client library
SYNOPSIS
#include <X11/extensions/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_base_return, int *error_base_return);
Status XResQueryVersion(Display *dpy, int *major_version_return, int *minor_ver-
sion_return);
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 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 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 fail-
ure.
ERRORS
XResQueryClientResources and XResQueryClientPixmapBytes will return BadValue if passed an
illegal client identifier.
