Returns the tabular data stream (TDS) packet size currently in use.
UINT dbgetpacket ( PDBPROCESS dbproc );
Is the DBPROCESS structure that is the handle for a particular workstation or Microsoft® SQL Server™ 2000 process. It contains all the information that DB-Library uses to manage communications and data between the workstation and SQL Server.
The TDS packet size currently in use.
To determine the TDS packet size in use, an application should call dbgetpacket after dbopen.
You can change the TDS packet size by using DBSETLPACKET, which sets the packet size field in the LOGINREC structure.
If the call to dbgetpacket fails (for example, when dbproc is null), dbgetpacket returns 0. Other than the failure case of 0, however, the call should never return less than 512 bytes.
