odm_rm_class Subroutine

Purpose

Removes an object class from the file system.

Library

Object Data Manager Library (libodm.a)

Syntax

#include <odmi.h>
int odm_rm_class (ClassSymbol)
CLASS_SYMBOL ClassSymbol;

Description

The odm_rm_class subroutine removes an object class from the file system. All objects in the specified class are deleted.

Parameter

ClassSymbol Identifies a class symbol returned from the odm_open_class subroutine. If the odm_open_class subroutine has not been called, this is the ClassName_CLASS structure created by the odmcreate command.

Return Values

Upon successful completion, a value of 0 is returned. If the odm_rm_class 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_rm_class subroutine sets the odmerrno variable to one of the following error codes:

ODMI_CLASS_DNE
                          The specified object class does not exist. Check path name and permissions.
ODMI_CLASS_PERMS
                          The object class cannot be opened because of the file permissions.
ODMI_INVALID_CLXN
                          Either the specified collection is not a valid object class collection or the collection does not contain consistent data.
ODMI_INVALID_PATH
                          The specified path does not exist on the file system. Make sure the path is accessible.
ODMI_MAGICNO_ERR
                          The class symbol does not identify a valid object class.
ODMI_OPEN_ERR
                          Cannot open the object class. Check path name and permissions.
ODMI_TOOMANYCLASSES
                          Too many object classes have been accessed. An application can only access less than 1024 object classes.
ODMI_UNLINKCLASS_ERR
                          Cannot remove the object class from the file system. Check path name and permissions.
ODMI_UNLINKCLXN_ERR
                          Cannot remove the object class collection from the file system. Check path name and permissions.
