DL_PassThrough

NAME
  DL_PassThrough, CSSM_DL_PassThrough - Extend data storage module
                                        functionality (CDSA)

SYNOPSIS
  # include <cssm.h>

   API:
       CSSM_RETURN CSSMAPI CSSM_DL_PassThrough
       (CSSM_DL_DB_HANDLE DLDBHandle,
       uint32 PassThroughId,
       const void *InputParams,
       void **OutputParam)
   SPI:
       CSSM_RETURN CSSMDLI DL_PassThrough
       (CSSM_DL_DB_HANDLE DLDBHandle,
       uint32 PassThroughId,
       const void *InputParams,
       void **OutputParam)

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 upon which the function is to be
          performed.

  PassThroughId (input)
          An identifier assigned by a DL module to indicate the
          exported function to be performed.

  InputParams (input)
          A pointer to a module implementation-specific structure
          containing parameters to be interpreted in a function-
          specific manner by the requested DL module.

  OutputParams (output)
          A pointer to a module, implementation-specific structure
          containing the output data. The service provider will
          allocate the memory for this structure. The application
          should free the memory for the structure.

DESCRIPTION
  This function allows applications to call data storage library
  module-specific operations that have been exported. Such operations
  may include queries or services that are specific to the domain
  represented by a DL module.

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.  See CDSA.

       CSSMERR_DL_INVALID_DB_HANDLE
       CSSMERR_DL_INVALID_PASSTHROUGH_ID
