DB_ENV->set_errpfx(DB_ENV *dbenv, const char *errpfx);
Description
Set the prefix string that appears before error messages issued by Berkeley DB.
The DB->set_errpfx and DB_ENV->set_errpfx functions do not copy
the memory to which the errpfx argument refers; rather, they
maintain a reference to it. Although this allows applications to modify
the error message prefix at any time (without repeatedly calling the
interfaces), it means the memory must be maintained until the handle is
closed.
The DB_ENV->set_errpfx interface may be used to configure Berkeley DB at any time
during the life of the application.
