DbEnv::set_errpfx

#include <db_cxx.h> void DbEnv::set_errpfx(const char *errpfx); Description Set the prefix string that appears before error messages issued by Berkeley DB. The Db::set_errpfx and DbEnv::set_errpfx methods 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 DbEnv::set_errpfx interface may be used to configure Berkeley DB at any time during the life of the application.
