-
- o dbtsnewval() is one of the DB-Library browse mode routines.
- See the Introduction for a detailed discussion of browse mode.
- o dbtsnewval() provides information about the timestamp column.
- The WHERE clause returned by dbqual() contains a call to the
- tsequal built-in function. When such a WHERE clause is used in
- an UPDATE statement, the tsequal function places a new value in
- the updated row's timestamp column and returns the new times-
- tamp value to the application (if the update is successful).
- This routine allows the application to save the new timestamp
- value, possibly for use with dbtsput().
-
- 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.

-
- RETURNS:
- A pointer to the updated row's new timestamp value. If no times-
- tamp was returned to the application (possibly because the update
- was unsuccessful, or because the UPDATE statement did not contain
- the tsequal built-in function), the pointer will be NULL.
