EXAMPLE
#include "mutnnn.h"
#include "rdsnnn.h"
#include "rwinnn.h"
#include "rtlnnn.h"
main()
{
rdsrec_list *Rectangle;
rdswinrec_list *WinRec, *HeadWinRec;
mbkenv();
rdsenv();
loadrdsparam();
WinRec = HeadWinRec = allocrdswinrec();
/* Fill the table with rectangles */
for ( Counter = 0 ; Counter < RWI_MAX_REC ; Counter ++ )
{
if ( Rectangle == (rdsrec_list *) NULL ) break;
WinRec->RECTAB[Counter] = Rectangle;
Rectangle = Rectangle->NEXT;
}
if ( Counter == RWI_MAX_REC )
{
/* the table is full : allocation of a new table */
WinRec->NEXT = allocrdswinrec();
WinRec = WinRec->NEXT;
