 NAME

   CL_CertGetNextFieldValue,
   CSSM_CL_CertGetNextFieldValue - Return the value of a certificate
                                   field (CDSA)

 SYNOPSIS

   # include <cssm.h>

        API:
        CSSM_RETURN CSSMAPI CSSM_CL_CertGetNextFieldValue
        (CSSM_CL_HANDLE CLHandle,
        CSSM_HANDLE ResultsHandle,
        CSSM_DATA_PTR *Value)
        SPI:
        CSSM_RETURN CSSMCLI CL_CertGetNextFieldValue
        (CSSM_CL_HANDLE CLHandle,
        CSSM_HANDLE ResultsHandle,
        CSSM_DATA_PTR *Value)

 LIBRARY

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

 PARAMETERS

   CLHandle (input)
           The handle that describes the add-in certificate library module
           used to perform this function.

   ResultsHandle (input)
           The handle that identifies the results of a certificate query.

   Value (output)
           A pointer to the structure containing the value of the
           requested field. The structure and the field at I
           "(*Value)->Data" are allocated by the service provider. The
           CSSM_CL_FreeFieldValue() (CSSM API) or CL_FreeFieldValue()
           (CL SPI), function can be used to deallocate *Value and
           (*Value)->Data.

 DESCRIPTION

   This function returns the value of a certificate field, when that
   field occurs multiple times in a certificate. Certificates with
   repeated fields (such as multiple signatures) have multiple field
   values corresponding to a single OID. A call to the function
   CSSM_CL_CertGetFirstFieldValue() (CSSM API), or
   CL_CertGetFirstFieldValue() (CL SPI), returns a results handle
   identifying the size and values contained in the result set. The
   CSSM_CL_CertGetNextFieldValue() (CSSM API), or
   CL_CertGetNextFieldValue() (CL SPI), function can be called repeatedly
   to obtain these values, one at a time. The result set does not change
   in size or value between calls to this function.

 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_CL_INVALID_RESULTS_HANDLE
        CSSMERR_CL_NO_FIELD_VALUES
