Base Operating System and Extensions Technical Reference, Volume 1

odm_close_class Subroutine

Purpose

Closes an ODM object class.

Library

Object Data Manager Library (libodm.a)

Syntax

#include <odmi.h>

int odm_close_class (ClassSymbol)
CLASS_SYMBOL ClassSymbol;

Description

The odm_close_class subroutine closes the specified object class.

Parameters

ClassSymbol

Specifies a class symbol identifier returned from an odm_open_class subroutine. If the odm_open_class subroutine has not been called, then this identifier is the ClassName_CLASS structure that was created by the odmcreate command.

Return Values

Upon successful completion, a value of 0 is returned. If the odm_close_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_close_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.
