RETCODE dbmnysub(dbproc, m1, m2, difference) DBPROCESS *dbproc; DBMONEY *m1; DBMONEY *m2; DBMONEY *difference;
A pointer to the DBPROCESS structure that provides the connection for a particular front-end/server process. It contains all the information that DB-Library uses to manage communications and data between the front end and the server.
This parameter may be NULL. The DBPROCESS is used as a parameter to an application’s error handler. It also contains information on what language to print error messages in. If a DBPROCESS is not supplied, the default national language is used.
