ALLOCRDSRECWIN(3)	    RDS	PHYSICAL FUNCTIONS	     ALLOCRDSRECWIN(3)

NAME
       allocrdsrecwin  - allocates a structure used to know windows which con-
       tains a rectangle.

SYNOPSIS
       #include	"rwinnn.h"
	rdsrecwin_list *allocrdsrecwin()

PARAMETER
       none

DESCRIPTION
       The allocrdsrecwin function allocates a rdsrecwin_list structure	 item.
       This  structure	contains a pointer to a	window structure so it permits
       to chain	all windows which contains a same rectangle (see librwi).

RETURN VALUE
       The pointer to the newly	allocated structure is returned.

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

EXAMPLE
	       #include	"mutnnn.h"
	       #include	"rdsnnn.h"
	       #include	"rwinnn.h"
	       #include	"rtlnnn.h"
	       # define	POINTER_WINDOW(R)				 \
									 \
		 (((UserStruct *)((char	*)(R)+sizeof(rdsrec_list)))->WINDOW )
	       typedef struct UserStruct
		{
		  rdsrecwin_list *WINDOW;
		} UserStruct;
	       main()
		 {
		    rdsfig_list	*Figure;
		    rdsrec_list	*Rectangle;
		    rdswin_list	*Window;
		    mbkenv();
		    rdsenv();
		    loadrdsparam();
		    Figure = addrdsfig(	"core",sizeof (	UserStruct ) );
		    Rectangle =
		      addrdsfigrec(Figure,"Alu1",RDS_ALU1,2,4,5,1);
		    POINTER_WINDOW (Rectangle) = allocrdsrecwin();
		    . .	. .
		    Window = ...
		    (POINTER_WINDOW (Rectangle))->WINDOW = Window;
		    . .	. .
		 }
