+
+   If an X error occurs which we are not expecting, we have no alternative
+   but to print it to stderr.  It would be nice to stuff it into a pop-up
+   buffer, or to print it in the minibuffer, but that's not possible, because
+   one is not allowed to do any I/O on the display connection from an error
+   handler. The guts of Xlib expect these functions to either return or exit.
+
+   However, there are occasions when we might expect an error to reasonably
+   occur.  The interface to this is as follows:
+
+   Before calling some X routine which may error, call
+	expect_x_error (dpy);
+
+   Just after calling the X routine, call either:
+
+	x_error_occurred_p (dpy);
+
+   to ask whether an error happened (and was ignored), or:
+
+	signal_if_x_error (dpy, resumable_p);
+
+   which will call Fsignal() with args appropriate to the X error, if there
+   was one.  (Resumable_p is whether the debugger should be allowed to
+   continue from the call to signal.)
+
+   You must call one of these two routines immediately after calling the X
+   routine; think of them as bookends like BLOCK_INPUT and UNBLOCK_INPUT.

+The first arg is the name of the resource to retrieve, such as \"font\".
+The second arg is the class of the resource to retrieve, like \"Font\".
+The third arg should be one of the symbols 'string, 'integer, 'natnum, or
+  'boolean, specifying the type of object that the database is searched for.
+The fourth arg is the locale to search for the resources on, and can
+  currently be a a buffer, a frame, a device, or 'global.  If omitted, it
+  defaults to 'global.
+The fifth arg is the device to search for the resources on. (The resource
+  database for a particular device is constructed by combining non-device-
+  specific resources such any command-line resources specified and any
+  app-defaults files found [or the fallback resources supplied by XEmacs,
+  if no app-defaults file is found] with device-specific resources such as
+  those supplied using xrdb.) If omitted, it defaults to the device of
+  LOCALE, if a device can be derived (i.e. if LOCALE is a frame or device),
+  and otherwise defaults to the value of `default-x-device'.
+The sixth arg NOERROR, if non-nil, means do not signal an error if a
+  bogus resource specification was retrieved (e.g. if a non-integer was
+  given when an integer was requested).  In this case, a warning is issued
+  instead.
+
+The resource names passed to this function are looked up relative to the
+locale.
+
+If you want to search for a subresource, you just need to specify the
+resource levels in NAME and CLASS.  For example, NAME could be
+\"modeline.attributeFont\", and CLASS \"Face.AttributeFont\".
+
+Specifically,
+
+1) If LOCALE is a buffer, a call
+
+    (x-get-resource \"foreground\" \"Foreground\" 'string SOME-BUFFER)
+
+is an interface to a C call something like
+
+    XrmGetResource (db, \"xemacs.buffer.BUFFER-NAME.foreground\",
+			\"Emacs.EmacsLocaleType.EmacsBuffer.Foreground\",
+			\"String\");
+
+2) If LOCALE is a frame, a call
+
+    (x-get-resource \"foreground\" \"Foreground\" 'string SOME-FRAME)
+
+is an interface to a C call something like
+
+    XrmGetResource (db, \"xemacs.frame.FRAME-NAME.foreground\",
+			\"Emacs.EmacsLocaleType.EmacsFrame.Foreground\",
+			\"String\");
+
+3) If LOCALE is a device, a call
+
+    (x-get-resource \"foreground\" \"Foreground\" 'string SOME-DEVICE)
+
+is an interface to a C call something like
+
+    XrmGetResource (db, \"xemacs.device.DEVICE-NAME.foreground\",
+			\"Emacs.EmacsLocaleType.EmacsDevice.Foreground\",
+			\"String\");
+
+4) If LOCALE is 'global, a call
+
+    (x-get-resource \"foreground\" \"Foreground\" 'string 'global)
+
+is an interface to a C call something like
+
+    XrmGetResource (db, \"xemacs.foreground\",
+			\"Emacs.Foreground\",
+			\"String\");
+
+Note that for 'global, no prefix is added other than that of the
+application itself; thus, you can use this locale to retrieve
+arbitrary application resources, if you really want to.
+
+The returned value of this function is nil if the queried resource is not
+found.  If the third arg is `string', a string is returned, and if it is
+`integer', an integer is returned.  If the third arg is `boolean', then the
+returned value is the list (t) for true, (nil) for false, and is nil to
+mean ``unspecified.''
