DB->set_errpfx(DB *db, const char *errpfx);
30
<p>Set the prefix string that appears before error messages issued by Berkeley DB.
31
<p>The DB->set_errpfx and <a href="../api_c/env_set_errpfx.html">DB_ENV->set_errpfx</a> methods do not copy
32
the memory to which the <b>errpfx</b> argument refers; rather, they
33
maintain a reference to it. Although this allows applications to modify
34
the error message prefix at any time (without repeatedly calling the
35
interfaces), it means the memory must be maintained until the handle is
37
<p>For <a href="../api_c/db_class.html">DB</a> handles opened inside of Berkeley DB environments, calling the
38
DB->set_errpfx method affects the entire environment and is equivalent to calling
39
the <a href="../api_c/env_set_errpfx.html">DB_ENV->set_errpfx</a> method.
40
<p>The DB->set_errpfx interface may be called at any time during the life of
