Db::set_errpfx

#include <db_cxx.h> void Db::set_errpfx(const char *errpfx); Description Set the prefix string that appears before error messages issued by Berkeley DB. The Db::set_errpfx method 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 Db::set_errpfx, but means that the memory must be maintained until the handle is closed. For Db handles opened inside of Berkeley DB environments, calling the Db::set_errpfx method affects the entire environment and is equivalent to calling the DbEnv::set_errpfx method. The Db::set_errpfx interface may be used to configure Berkeley DB at any time during the life of the application.
