NAME

CSSM_DL_DataInsert — Create new persistent data record (CDSA)

SYNOPSIS

# include <cssm.h>
API:
CSSM_RETURN CSSMAPI CSSM_DL_DataInsert
(CSSM_DL_DB_HANDLE DLDBHandle,
CSSM_DB_RECORDTYPE RecordType,
const CSSM_DB_RECORD_ATTRIBUTE_DATA *Attributes,
const CSSM_DATA *Data,
CSSM_DB_UNIQUE_RECORD_PTR *UniqueId)
SPI:
CSSM_RETURN CSSMDLI DL_DataInsert
(CSSM_DL_DB_HANDLE DLDBHandle,
CSSM_DB_RECORDTYPE RecordType,
const CSSM_DB_RECORD_ATTRIBUTE_DATA *Attributes,
const CSSM_DATA *Data,
CSSM_DB_UNIQUE_RECORD_PTR *UniqueId)

LIBRARY

Common Security Services Manager library (cdsa$incssm300_shr.exe)

PARAMETERS

DLDBHandle (input)
  

The handle pair that describes the add-in data storage library module to be used to perform this function and the open data store in which to insert the new data record.

RecordType (input)
  

Indicates the type of data record being added to the data store.

Attributes (input/optional)
  

A list of structures containing the attribute values to be stored in that attribute, and the meta information (schema) describing those attributes. The list contains at most one entry per attribute in the specified record type. The specified AttributeFormat for each attribute must match that of the database schema, otherwise the error CSSMERR_DL_INCOMPATIBLE_FIELD_FORMAT is returned. If an attribute is of type CSSM_DB_ATTRIBUTE_FORMAT_STRING and the value specified for that string includes a null-terminator, then the length count in the CSSM_DATA structure containing the input string should include the terminating character. (If null-terminators are used, they should be used consistently when storing, searching, and retrieving the string value, otherwise selection predicates will not locate expected matches.) For those attributes that are not assigned values by the caller, the DL module may assume the values to be the empty set, or assume default values, or return an error. If the specified record type does not contain any attributes, this parameter must be NULL.

Data (input/optional)
  

A pointer to the CSSM_DATA structure which contains the opaque data object to be stored in the new data record. If the specified record type does not contain an opaque data object, this parameter must be NULL.

UniqueId (output)
  

A pointer to a CSSM_DB_UNIQUE_RECORD_PTR containing a unique identifier associated with the new record. This unique identifier structure can be used in future references to this record during the current open data base session. The pointer will be set to NULL if the function fails. The CSSM_DL_FreeUniqueRecord() function must be used to deallocate this structure.

DESCRIPTION

This function creates a new persistent data record of the specified type by inserting it into the specified data store. The values contained in the new data record are specified by the Attributes and the Data. The attribute value list contains zero or more attribute values. The Attributes parameter also specifies a record type. This type must be the same as the type specified by the RecordType input parameter. The DL module may require initial values for the CSSM pre-defined attributes. The DL module can assume default values for any unspecified attribute values or can return an error condition when DLM-required attribute values are not specified by the caller. The Data is an opaque object to be stored in the new data record.

If a primary key (concatination of all unique indexes in the relation) exists, the error CSSMERR_DL_INVALID_UNIQUE_INDEX_DATA is returned. The client should call CSSM_DL_DataGetFirst(), followed by CSSM_DL_DataModify() to change an existing record.

RETURN VALUE

A CSSM_RETURN value indicating success or specifying a particular error condition. The value CSSM_OK indicates success. All other values represent an error condition.

ERRORS

Errors are described in the CDSA Technical Standard.

CSSMERR_DL_FIELD_SPECIFIED_MULTIPLE
CSSMERR_DL_INCOMPATIBLE_FIELD_FORMAT
CSSMERR_DL_INVALID_FIELD_NAME
CSSMERR_DL_INVALID_DB_HANDLE
