###

    #include <db.h>

    void
    DB->set_errpfx(DB *db, const char *errpfx);

# Description

Set the prefix string that appears before error messages issued by Berkeley DB.

The DB->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 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 function affects the entire environment and is equivalent to calling the DBENV->set_errpfx function.

The DB->set_errpfx interface may be used to configure Berkeley DB at any time during the life of the application.
