###

    #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 DbEnv::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 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.
