<h1>Description</h1>
<p>Applications installing application-specific recovery methods need
to be called before Berkeley DB performs recovery so they may add their recovery
methods to Berkeley DB's.
<p>The DbEnv::set_recovery_init method supports this functionality. The
<b>db_recovery_init_fcn</b> method must be declared with one
argument, a reference to the enclosing Berkeley DB environment. This
method will be called after the <a href="../api_cxx/env_open.html">DbEnv::open</a> has been called,
but before recovery is started.
<p>If the <b>db_recovery_init_fcn</b> method returns a non-zero value,
no recovery will be performed and <a href="../api_cxx/env_open.html">DbEnv::open</a> will return the same
value to its caller.
<p>The DbEnv::set_recovery_init interface may only be used to configure Berkeley DB before
the <a href="../api_cxx/env_open.html">DbEnv::open</a> interface is called.
<p>The DbEnv::set_recovery_init method either returns a non-zero error value or throws an exception that
encapsulates a non-zero error value on failure, and returns 0 on success.
<h1>Errors</h1>
<p><dl compact>
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
<p>Called after <a href="../api_cxx/env_open.html">DbEnv::open</a> was called.
