 SYNOPSIS

        (CSSM_TP_HANDLE TPHandle,
        CSSM_CL_HANDLE CLHandle,
        CSSM_CC_HANDLE CCHandle,
        const CSSM_DL_DB_LIST *DBList,

    SPI:

        (CSSM_TP_HANDLE TPHandle,
        CSSM_CL_HANDLE CLHandle,
        CSSM_CC_HANDLE CCHandle,
        const CSSM_DL_DB_LIST *DBList,
        uint32 PassThroughId,
        const void *InputParams,
        void **OutputParams)

 LIBRARY
   Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

 PARAMETERS
   TPHandle (input)
           The handle that describes the add-in trust policy module
           used to perform this function.

   CLHandle (input/optional)
           The handle that describes the add-in certificate library
           module that can be used to manipulate the subject certificate
           and anchor certificates.  If no certificate library module is
           specified, the TP module uses an assumed CL module, if required.

   CCHandle (input/optional)
           The handle that describes the context of the cryptographic
           operation.  If the module-specific operation does not perform
           any cryptographic operations, a cryptographic context is not
           required

   DBList (input/optional)
           A list of handle pairs specifying a data storage library module
           and a data store, identifying certificate databases containing
           certificates (and possibly other security objects) that may be
           used by the pass-through function. If no DL and DB handle pairs
           are specified, the TP module can use an assumed DL module and
           an assumed data store for this operation.

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

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

   OutputParams (output/optional)
           A pointer to a module, implementation-specific structure
           containing the output data. The service provider allocates
           the memory for substructures. The application must free the
           memory for the substructures.

 DESCRIPTION
   This function allows applications to call trust policy module-
   specific operations that have been exported. Such operations may
   include queries or services specific to the domain represented by
   the TP 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.
