(CSSM_CL_HANDLE CLHandle, const CSSM_DATA *Crl, const
CSSM_OID *CrlField, CSSM_HANDLE_PTR ResultsHandle, uint32

CSSM_RETURN CSSMCLI CL_CrlGetFirstFieldValue (CSSM_CL_HANDLE

Common Security Services Manager library (libcssm.so)
The handle that describes the add-in Certificate Library
module used to perform this function. A pointer to the
CSSM_DATA structure that contains the CRL from which the
field is to be retrieved. An object identifier that identifies
the field value to be extracted from the CRL. A
pointer to the CSSM_HANDLE that should be used to obtain
any additional matching fields. The total number of
fields that match the CrlField OID. This count includes
the first match, which was returned by this function. 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.
This function returns the value of the CRL field designated
by the CSSM_OID CrlField. The OID also identifies
the data format for the field value returned to the
caller. If multiple OIDs name the same CRL field, then
each OID defines a distinct data format for the returned
field value. The function CSSM_CL_CrlDescribeFormat()
(CSSM API), or CL_CrlDescribeFormat() (CL SPI), provides a
list of all CSSM_OID values supported by a Certificate
Library module for naming fields of a CRL.
If more than one field matches the CrlField OID, the first
matching field will be returned. The number of matching
fields is an output parameter, as is the ResultsHandle to
be used to retrieve the remaining matching fields.
The set of matching fields is determined by this function.
The number of matching fields and the field values do not
change between this function and subsequent calls to
CSSM_CL_CrlGetNextFieldValue() (CSSM API), or CL_CrlGetNextFieldValue()
(CL SPI).
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 are described in the CDSA technical standard. See
