XSaveContext(3X11)	       XLIB FUNCTIONS		   XSaveContext(3X11)



NAME
  XSaveContext, XFindContext, XDeleteContext, XUniqueContext - associative
  look-up routines

SYNTAX
  int XSaveContext(display, rid, context, data)
	Display *display;
	XID rid;
	XContext context;
	XPointer data;

  int XFindContext(display, rid, context, data_return)
	Display *display;
	XID rid;
	XContext context;
	XPointer *data_return;

  int XDeleteContext(display, rid, context)
	Display *display;
	XID rid;
	XContext context;

  XContext XUniqueContext()

ARGUMENTS

  context   Specifies the context type to which the data belongs.

  data	    Specifies the data to be associated with the window and type.

  data_return
	    Returns the data.

  display   Specifies the connection to the X server.

  rid	    Specifies the resource ID with which the data is associated.

DESCRIPTION
  If an entry with the specified resource ID and type already exists,
  XSaveContext overrides it with the specified context.	 The XSaveContext
  function returns a nonzero error code if an error has occurred and zero
  otherwise.  Possible errors are XCNOMEM (out of memory).

  Because it is a return value, the data is a pointer.	The XFindContext
  function returns a nonzero error code if an error has occurred and zero
  otherwise.  Possible errors are XCNOENT (context-not-found).

  The XDeleteContext function deletes the entry for the given resource ID and
  type from the data structure.	 This function returns the same error codes
  that XFindContext returns if called with the same arguments.	XDeleteCon-
  text does not free the data whose address was saved.


  The XUniqueContext function creates a unique context type that may be used
  in subsequent calls to XSaveContext.
