Passthrough routines can be called in Open Server gateway applications. They allow a DB-Library/C application to send and receive whole Tabular Data Stream™ (TDS) packets and set TDS packet size.
TDS is an application protocol used for the transfer of requests and request results between clients and servers. These routines are used with the srvrecvpassthru and srvsendpassthru Open Server Server-Library routines:
dbrecvpassthru – receives a TDS packet from Open Server.
dbsendpassthru – sends a TDS packet to Open Server.
See the Open Server Server-Library/C Reference Manual for descriptions of srvrecvpassthru and srvsendpassthru.
