CSSM_TP_RetrieveCredResult
NAME
CSSM_TP_RetrieveCredResult - Return the results of the credentials
request (CDSA)
SYNOPSIS
# include <cssm.h>
CSSM_RETURN CSSMAPI CSSM_TP_RetrieveCredResult
(CSSM_TP_HANDLE TPHandle,
const CSSM_DATA *ReferenceIdentifier,
const CSSM_TP_CALLERAUTH_CONTEXT *CallerAuthCredentials,
sint32 *EstimatedTime,
CSSM_BOOL *ConfirmationRequired,
CSSM_TP_RESULT_SET_PTR *RetrieveOutput)
LIBRARY
Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)
PARAMETERS
TPHandle (input)
The handle that describes the certification authority module
used to perform this function.
ReferenceIdentifier (input)
A reference identifier that uniquely identifies the
CSSM_TP_SubmitCredRequest() call that initiated the
certificate service request whose results are returned by
this function. The identifier persists across application
executions and becomes undefined when all local processing
of the request has completed.
Local processing is completed in one of two ways:
· For certificate services that do not require explicit
confirmation by the requester, the reference identifier
is invalidated when the corresponding
CSSM_TP_RetrieveCredResult() function completes (by
returning valid results or by failure, which blocks
returned results).
· For certificate services that require explicit confirmation
by the requester, the reference identifier is invalidated
by successfully invoking the function
CSSM_TP_ConfirmCredResult().
CallerAuthCredentials (input/optional)
This structure contains a set of caller authentication
credentials. The authentication information can be a
passphrase, a PIN, a completed registration form, a
certificate, or a template of user-specific data. The
required set of credentials is defined by the service
provider module and recorded in a record in the MDS Primary
relation. Multiple credentials can be required. If the local
service provider module does not require credentials from a
caller, then the Credentials field of this verification
context structure can be NULL. The structure optionally
contains additional credentials that can be used to support
the authentication process. Authentication credentials
required by the authority should be included in the
RequestInput. The local TP module can forward information
from CallerAuthCredentials to the authority, as appropriate,
but is not required to do so.
EstimatedTime (output)
The number of seconds estimated before the results of a
requested service will be returned to the requester. When the
local TP module or the authority process cannot estimate the
time required to perform the requested service, the output
value for estimated time is CSSM_ESTIMATED_TIME_UNKNOWN.
ConfirmationRequired (output)
A Boolean value indicating whether the caller must invoke
CSSM_TP_ConfirmCredResult() to acknowledge retrieving the
results of the service request. CSSM_TRUE indicates the
caller must call CSSM_TP_ConfirmCredResult(). CSSM_FALSE
indicates that the caller must not call
CSSM_TP_ConfirmCredResult(). The value of this output
parameter is not applicable until CSSM_TP_RetrieveCredResult()
completes by returning results of the request or terminates
in unrecoverable failure.
RetrieveOutput (output)
A pointer to the results returned by the authority in
response to the service requests submitted by
CSSM_TP_SubmitCredRequest(). The output results are ordered
corresponding to the requests. The structure of the
response set is determined by the type of request. The
caller and the service provider must retain knowledge of
the request type associated with the ReferenceIdentifier.
DESCRIPTION
This function returns the results of a CSSM_TP_SubmitCredRequest()
call.
The single identifier ReferenceIdentifier denotes the
CSSM_TP_SubmitCredRequest() invocation that initiated the request.
It is possible that the results are not ready to be retrieved when
this call is made. In that case, an EstimatedTime to complete
processing is returned. The caller must attempt to retrieve the
results again after the estimated time to completion has elapsed.
This function can fail in total for any one of the following reasons:
· The reference identifier is invalid.
· The TP process cannot be located.
· The TP process encountered a fatal error when attempting to
process the requests.
When this function completes, the set of return results is ordered
corresponding to the order of the originating request.
Some certificate services require the requester to confirm retrieval
of the results. The ConfirmationRequired parameter indicates whether
the caller must confirm completion of CSSM_TP_RetrieveCredResult()
by calling CSSM_TP_ConfirmCredResult().
RETURN VALUE
A CSSM_RETURN value combined with estimated time to indicate one of
three results:
Complete Function Function Return RetrieveOutput EstimatedTime
Result Value
----------------- --------------- -------------- -------------
Request results CSSM_OK Non-NULL pointer NA
returned to caller
Request results not CSSM_OK NULL pointer CSSM_ESTIMATED_
ready, but expected TIME_UNKNOWN or
in the future <estimated seconds>
Fatal Error, results (!CSSM_OK) NA NA
will never be
returned
The (!CSSM_OK) return value represents a specific error code.
