int
DBENV->set_verbose(DB_ENV *dbenv, u_int32_t which, int onoff);
Description
The DBENV->set_verbose function turns additional informational and
debugging messages in the Berkeley DB message output on and off. If
onoff is set to
non-zero,
the additional messages are output.
The which parameter must be set to one of the following values:
Display the waits-for table when doing deadlock detection.
The DBENV->set_verbose interface may be used to configure Berkeley DB at any time
during the life of the application.
The DBENV->set_verbose function returns a non-zero error value on failure and 0 on success.
The database environment's verbosity may also be set using the environment's
DB_CONFIG file. The syntax of the entry in that file is a
single line with the string "set_verbose", one or more whitespace characters,
and the interface which argument as a string, for example,
"set_verbose DB_VERB_CHKPOINT". Because the DB_CONFIG file is read when the database
environment is opened, it will silently overrule configuration done
before that time.
