15 Rectangle The rectangle to add to the windowing.
16 RdsWindow The head of the windowing which has to contain the
18 rectangle.

21 The addrdsrecwindow function inserts a rdsrec_list rectangle structure
22 in the windowing of the rds structure. The rectangle is added in one or
23 many windows of the table (it depends on his dimensions). The field
24 ´USER´ of the rectangle is used to point to the list of windows which
25 contains the rectangle. So, the field ´USER´ has to be saved in an
26 added structure to the rdsrec_list structure if librfm functions are
27 used because some use the field ´USER´ to link rectangles (see librds
28 about field ´USER´).
29 Note If the rectangle is contained in only one window, then the field
31 ´USER´ points to a "rdswin_list" window structure.
32 If the rectangle is contained in many windows, the field ´USER´
33 points to a "rdsrecwin_list" structure which is a list which
34 contains windows.
35 To know if a rectangle belongs to one or many windows, use the macro
37 IsRdsOneWindow defined in librwi.
