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 contains 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
