odm_rm_obj Subroutine

Purpose

Removes objects from an ODM object class.

Library

Object Data Manager Library (libodm.a)

Syntax

#include <odmi.h>
int odm_rm_obj (ClassSymbolCriteria)
CLASS_SYMBOL ClassSymbol;
char *Criteria;

Description

The odm_rm_obj subroutine deletes objects from an object class.

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.
Criteria Contains as a string the qualifying criteria for selecting the objects to remove.

Return Values

Upon successful completion, the number of objects deleted is returned. If the odm_rm_obj 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_obj subroutine sets the odmerrno variable to one of the following error codes:

ODMI_BAD_CRIT
                          The specified search criteria is incorrectly formed. Make sure the criteria contains only valid descriptor names and the search values are correct.
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_INTERNAL_ERR
                          An internal consistency problem occurred. Make sure the object class is valid or contact the person responsible for the system.
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_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.

This subroutine is part of Base Operating System (BOS) Runtime.
