<h1>Description</h1>
<p>
The db_appexit function closes the initialized Berkeley DB subsystems, freeing
any allocated resources and closing any underlying subsystems.
<p>
In multi-threaded applications, only a single thread may call
db_appexit.
<p>
The db_appexit
function returns the value of <b>errno</b> on failure, and 0 on success.
<p>
<h1>Errors</h1>
If a fatal error occurs in Berkeley DB, the db_appexit function may fail and return
DB_RUNRECOVERY, at which point all subsequent database calls will also
return DB_RUNRECOVERY.
<p>
The db_appexit
function may fail and return <b>errno</b>
for any of the errors specified for the following Berkeley DB and C library
functions:
free(3),
<a href="../../api_c/DbLockTab/close.html">lock_close</a>,
<a href="../../api_c/DbLog/close.html">log_close</a>,
<a href="../../api_c/DbMpool/close.html">memp_close</a>,
memset(3),
strlen(3),
and
