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
