DBENV->set_verbose

#include <db.h> 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: DB_VERB_CHKPOINT Display checkpoint location information when searching the log for checkpoints. DB_VERB_DEADLOCK Display additional information when doing deadlock detection. DB_VERB_RECOVERY Display additional information when performing recovery. DB_VERB_WAITSFOR 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 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". Configuration in the DB_CONFIG file silently overrules configuration done using the DBENV->set_verbose function. Errors EINVAL An invalid flag value or parameter was specified.
