SYNOPSIS
  # include <cdsa/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 (libcssm.so)

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

  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

  condition. The value CSSM_OK indicates success. All other values represent
  an error condition.
