XSaveContext(3) 				    XLIB FUNCTIONS				      XSaveContext(3)

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

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

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

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

       XContext XUniqueContext(void);

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 speci-
       fied context.  The XSaveContext function returns a nonzero error code if an error has occurred and zero other-
       wise.  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.
       XDeleteContext 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 XSaveCon-
       text.
