# rdsfree(3)

free memory place

## NAME

 rdsfree - free memory place

## SYNOPSYS

```
 #include "rdsnnn.h"
  void  rdsfree( Pointer, Size )
    char         ∗Pointer;
    unsigned int  Size;
```

## PARAMETER

- *Pointer*

  pointer to the memory to free.

- *Size*

  Size of the memory to free.

## DESCRIPTION

The *rdsfree* function deletes memory of *size*=´Size´ allocated with rdsalloc function. If the parameter Size is set to ZERO (or RDS\_ALLOC\_BLOCK) then the memory is deleted by BLOCK else the memory is deleted by HEAP.

*Note* : A memory allocated by BLOCK (resp. by HEAP) must be deleted by BLOCK (resp. by HEAP).

## RETURN VALUE

nothing

## ERRORS

none

## EXAMPLE

```
          #include "rdsnnn.h"
	    main()
	     {
	       rdsrec_list ∗Rectangle;
	       rdsfig_list ∗Figure;
               Figure    = allocrdsfig ();
	       Rectangle = allocrdsrec ();
	       Rectangle->X  = 20;
	       Rectangle->Y  = 20;
	       Rectangle->DX = 48;
	       Rectangle->DY = 8;
	       ...
	       /∗ ∗/ rdsfree ( Rectangle, sizeof (rdsrec_list));
               /∗ deletes a figure allocated by block ∗/
               /∗ ∗/ rdsfree ( Figure , RDS_ALLOC_BLOCK);
	     }
