Library

Object Data Manager Library (libodm.a)

Syntax

#include <odmi.h>
int odm_free_list ( ReturnData,  DataInfo)
struct ClassName *ReturnData;
struct listinfo *DataInfo;

Description

The odm_free_list subroutine recursively frees up a tree of memory object lists that were allocated for an odm_get_list subroutine.

Parameters

Item Description
ReturnData Points to the array of ClassName structures returned from the odm_get_list subroutine.
DataInfo Points to the listinfo structure that was returned from the odm_get_list subroutine. The listinfo structure has the following form: 
struct listinfo {
char ClassName[16];      /* class name for query */
char criteria[256];      /* query criteria */
int num;                 /* number of matches found */
int valid;               /* for ODM use */
CLASS_SYMBOL class;      /* symbol for queried class */
};

Return Values

Upon successful completion, a value of 0 is returned. If the odm_free_list subroutine is unsuccessful, a value of -1 is returned and the odmerrno variable is set to an error code.

Error Codes

Failure of the odm_free_list subroutine sets the odmerrno variable to one of the following error codes:
