<h1>Description</h1>
|
|
<p>Toggle the Berkeley DB panic state. Setting <b>panic</b> to a non-zero value
|
|
causes Berkeley DB to refuse attempts to call Berkeley DB functions with the
|
|
<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a> error return.
|
|
<p>The DbEnv::set_panicstate interface affects the entire application, not a single
|
|
database or database environment.
|
|
<p>While the DbEnv::set_panicstate interface may be used to configure Berkeley DB at any time
|
|
during the life of the application, it should normally be called before
|
|
making any calls to the <a href="../api_c/env_create.html">db_env_create</a> or <a href="../api_c/db_create.html">db_create</a> methods.
|
|
<p>The DbEnv::set_panicstate 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.
|
