NAME

6       delrdsrecwindow  - deletes a rectangle from the windowing of rds struc‐
7       ture.
8

SYNOPSIS

10       #include "rwinnn.h"
11       void delrdsrecwindow( Rectangle, RdsWindow )
12          rdsrec_list ∗Rectangle;
13          rdswindow   ∗RdsWindow;
14

PARAMETER

16       Rectangle           The rectangle to delete from the windowing.
17
18       RdsWindow           Pointer to the windowing of rds structure.
19

DESCRIPTION

21       The delrdsrecwindow function deletes a rectangle from the windowing  of
22       the  rds structure. Some fields of the rectangle structure are modified
23       :
24       Field ´USER´ is set to NULL.
25       Field ´FLAGS´ is modified (bits about the windowing - see librds :  the
26       field ´FLAGS´ of rdsrec_list structure).
27

RETURN VALUE

29       nothing

ERRORS

32       none
