- ______________________________________________________________________
-
- o This routine lets the application know if the DB-Library net-
- work buffer contains any bytes yet unread.
- o DBRBUF() is ordinarily used in conjunction with dbsqlok() and
- DBIORDESC() to manage multiple input data streams. To manage
- these input streams efficiently, an application that uses
- dbsqlok() should check whether any bytes remain either in the
- network buffer (by calling DBRBUF()) or in the network itself
- (by calling the UNIX select()) before it calls dbresults().
- See the DB-Library Reference Supplement for an example of this.
-
- PARAMETERS:
- dbproc - A pointer to the DBPROCESS structure that provides the
- connection for a particular front-end/SQL Server process. It
- contains all the information that DB-Library uses to manage
- communications and data between the front end and SQL Server.
