NAME    [Toc]    [Back]

       DL_DbOpen, CSSM_DL_DbOpen - Open a data store (CDSA)

SYNOPSIS    [Toc]    [Back]

       # include <cdsa/cssm.h>

       API:  CSSM_RETURN  CSSMAPI  CSSM_DL_DbOpen (CSSM_DL_HANDLE
       DLHandle,  const  char  *DbName,  const   CSSM_NET_ADDRESS
       *DbLocation,   CSSM_DB_ACCESS_TYPE   AccessRequest,  const
       CSSM_ACCESS_CREDENTIALS *AccessCred, const  void  *OpenParameters,
  CSSM_DB_HANDLE *DbHandle) SPI: CSSM_RETURN CSSMDLI
  DL_DbOpen  (CSSM_DL_HANDLE  DLHandle,   const   char
       *DbName,      const      CSSM_NET_ADDRESS     *DbLocation,
       CSSM_DB_ACCESS_TYPE AccessRequest, const  CSSM_ACCESS_CREDENTIALS
    *AccessCred,   const   void   *OpenParameters,
       CSSM_DB_HANDLE *DbHandle)

LIBRARY    [Toc]    [Back]

       Common Security Services Manager library (libcssm.so)

PARAMETERS    [Toc]    [Back]

       The handle that describes the add-in data storage  library
       module  to be used to perform this function.  A pointer to
       the string containing the logical name of the data  store.
       A  pointer  to  a  network  address directly or indirectly
       identifying the location of the storage  service  process.
       If  the  input is NULL, the module can determine a storage
       service process and its location based on the DbName  (for
       existing data stores) or can assume a default storage service
 process location. If the DbName does not  distinguish
       the  storage  service  process, the service cannot be performed
 and the  operation  fails.   An  indicator  of  the
       requested  access  mode  for the data store, such as readonly
 or read-write.  A pointer to the set of one  or  more
       credentials  being  presented  for  authentication  by the
       caller. These credentials are required to obtain access to
       the  specified  data  store. The credentials structure can
       contain multiple types of  credentials,  as  required  for
       multi-factor authentication. The credential data can be an
       immediate value, such as a passphrase,  PIN,  certificate,
       or template of user-specific data, or the caller can specify
 a callback function the DL can use to  obtain  one  or
       more  credentials.  The  required  set  of  credentials to
       access a particular data store is defined  by  the  DbInfo
       record  containing meta-data for the specified data store.
       If credentials are not required to  access  the  specified
       data  store,  then this field can be NULL.  A pointer to a
       module-specific set of parameters  required  to  open  the
       data  store.   The  handle  to  the opened data store. The
       value will be set to CSSM_INVALID_HANDLE if  the  function
       fails.

DESCRIPTION    [Toc]    [Back]

       This function opens the data store with the specified logical
 name under the specified access mode. If user authentication
  credentials are required, they must be provided.
       Also, additional open parameters may be required to open a
       given  data store, and are supplied in the OpenParameters.



RETURN VALUE    [Toc]    [Back]

       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    [Toc]    [Back]

       Errors are described in the CDSA technical standard.   See
       CDSA_intro(3).           CSSMERR_DL_DB_LOCKED         CSSMERR_DL_INVALID_ACCESS_REQUEST
 CSSMERR_DL_INVALID_DB_LOCATION
 CSSMERR_DL_INVALID_DB_NAME CSSMERR_DL_DATASTORE_DOESNOT_EXIST
      CSSMERR_DL_INVALID_PARSING_MODULE      CSSMERR_DL_INVALID_OPEN_PARAMETERS
