The TRSecureParams Record

The ASDSP parameter block is a variant parameter block that includes a field that is a record of type TRSecureParams, which defines the additional parameters required for an ASDSP session. This section shows the declaration for the TRSecureParams record. The routine description "sdspOpen" beginning on page 5-54 includes the field definitions for the TRSecureParams record.

The TRSecureParams record is defined as follows:

TYPE  TRSecureParams = 
PACKED RECORD
   localCID:            Integer;       {local connection ID}
   remoteCID:           Integer;       {remote connection ID}

                                       { and length = sdspWorkSize}
   recipient:           AuthIdentity;  {identity of recipient or initiator }
                                       { if active mode}
   issueTime:           UTCTime;       {time when credentials were issued}
   expiry:              UTCTime;       {time when credentials expire}
   initiator:           RecordIDPtr;   {RecordID of initiator returned in }
                                       { buffer pointed to by this field}
