CL_CertGetNextFieldValue(3)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
The handle that describes the add-in certificate library module used to
perform this function. The handle that identifies the results of a
certificate query. 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 corre‐
sponding to a single OID. A call to the function CSSM_CL_CertGetFirst‐
FieldValue() (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 repre‐
sent an error condition.
ERRORS
Errors are described in the CDSA technical standard. See
