NAME

       addrdsrecwindow - adds a rectangle in the windowing of rds structure.

SYNOPSYS

       #include "rwinnn.h"
	void addrdsrecwindow( Rectangle, RdsWindow )
	   rdsrec_list *Rectangle;
	   rdswindow   *RdsWindow;

PARAMETER

       Rectangle	   The rectangle to add to the windowing.

       RdsWindow	   The head of the windowing which has to contain the rectangle.

DESCRIPTION

       The addrdsrecwindow function inserts a rdsrec_list rectangle structure in the windowing of the rds structure. The rectangle is added in one
       or  many  windows  of  the  table (it depends on his dimensions). The field 'USER' of the rectangle is used to point to the list of windows
       which contains the rectangle. So, the field 'USER' has to be saved in an added structure to the rdsrec_list structure if  librfm  functions
       are used because somes use the field 'USER' to link rectangles (see librds about field 'USER').

       Note   If the rectangle is contained in only one window, then the field 'USER' points to a "rdswin_list" window structure.
	      If  the  rectangle  is contained in many windows, the field 'USER' points to a "rdsrecwin_list" structure which is a list which con-
	      tains windows.

       To know if a rectangle belongs to one or many windows, use the macro IsRdsOneWindow defined in librwi.

RETURN VALUE

       none

ERRORS

       "Rds202: rdsalloc error, can't continue !"
	      it's impossible to allocate the memory size desired
