CL_CertGetNextFieldValue

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
