Determine whether a particular DBPROCESS is dead.
DBBOOL DBDEAD(dbproc) DBPROCESS *dbproc;
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 server.
“True” or “False.”
This macro indicates whether or not the specified DBPROCESS has been marked dead. It is particularly useful in user-supplied error handlers.
If a DBPROCESS is dead, then almost every DB-Library routine that receives it as a parameter will immediately fail, calling the user-supplied error handler.
If there is no user-supplied error handler, a dead DBPROCESS
will cause the affected DB-Library routines not to fail, but to
abort.
Note that DBDEAD does not communicate with the server, but only checks the current status of a DBPROCESS. If a previously called DB-Library routine has not marked a DBPROCESS as dead, DBDEAD reports the DBPROCESS as healthy.
