odm_rm_by_id Subroutine

Purpose

Removes objects specified by their IDs from an ODM object class.

Library

Object Data Manager Library (libodm.a)

Syntax

#include <odmi.h>
int odm_rm_by_id(ClassSymbolObjectID)
CLASS_SYMBOL ClassSymbol;
int ObjectID;

Description

The odm_rm_by_id subroutine is called to delete an object from an object class. The object to be deleted is specified by passing its object ID from its corresponding ClassName structure.

Parameters

ClassSymbol Identifies a class symbol returned from an odm_open_class subroutine. If the odm_open_class subroutine has not been called, this is the ClassName_CLASS structure that was created by the odmcreate command.
ObjectID Identifies the object. This information is retrieved from the corresponding ClassName structure of the object class.

Return Values

Upon successful completion, a value of 0 is returned. If the odm_rm_by_id 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_by_id 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_FORK
                          Cannot fork the child process. Make sure the child process is executable and try again.
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_MALLOC_ERR
                          Cannot allocate sufficient storage. Try again later or contact the person responsible for the system.
ODMI_NO_OBJECT
                          The specified object identifier did not refer to a valid object.
ODMI_OPEN_ERR
                          Cannot open the object class. Check path name and permissions.
ODMI_OPEN_PIPE
                          Cannot open a pipe to a child process. Make sure the child process is executable and try again.
ODMI_PARAMS
                          The parameters passed to the subroutine were not correct. Make sure there are the correct number of parameters and that they are valid.
ODMI_READ_ONLY
                          The specified object class is opened as read-only and cannot be modified.
ODMI_READ_PIPE
                          Cannot read from the pipe of the child process. Make sure the child process is executable and try again.
ODMI_TOOMANYCLASSES
                          Too many object classes have been accessed. An application can only access less than 1024 object classes.
