DBENV->set_errpfx

#include <db.h> void DBENV->set_errpfx(DB_ENV *dbenv, const char *errpfx); Description Set the prefix string that appears before error messages issued by Berkeley DB. The DBENV->set_errpfx function does not copy the memory referenced by the errpfx argument, rather, it maintains a reference to it. This allows applications to modify the error message prefix at any time, without repeatedly calling DBENV->set_errpfx, but means that the memory must be maintained until the handle is closed. The DBENV->set_errpfx interface may be used to configure Berkeley DB at any time during the life of the application.
