CL_CertGetNextFieldValue(3)
NAME
  CL_CertGetNextFieldValue, CSSM_CL_CertGetNextFieldValue - Return the value
  of a certificate field (CDSA)

SYNOPSIS
  # include <cdsa/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 (libcssm.so)

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_intro(3).

       CSSMERR_CL_INVALID_RESULTS_HANDLE
       CSSMERR_CL_NO_FIELD_VALUES
