freerdsrec(3) - Linux man page

Name

freerdsrec - free memory associated to a rectangle

Synopsys

 #include "rdsnnn.h"
  void freerdsrec( Rectangle, Size )
    rdsrec_list  ∗Rectangle;
    unsigned int  Size;

Parameter

Rectangle Pointer of the rectangle structure to free. Size Size of the structure added (if it exists) to rdsrec_list structure.

Description

This function deletes the memory associated to the rectangle. Memory used is both memory of rdsrec_list structure and memory of the structure added by the user. If the user structure doesn't exist, the parameter 'Size' must be to 0L. Memory place used by the Pointers of the rdsrec_list structure (and the added structure) is not deleted so the user has to free these pointers before calling the freerdsrec() function.

Return Value

nothing

Errors

none

Example

           #include "mutnnn.h"
           #include "rdsnnn.h"
           #include "rtlnnn.h"
