<b>Description: DbLockNotGrantedException</b>
<p>This information describes the DbLockNotGrantedException class and
how it is used by the various Db* classes.</p>
<p>A DbLockNotGrantedException is thrown when a lock requested using
the <a href="../api_cxx/lock_get.html">DbEnv::lock_get</a> or <a href="../api_cxx/lock_vec.html">DbEnv::lock_vec</a> methods, where the <a href="../api_cxx/lock_vec.html#DB_LOCK_NOWAIT">DB_LOCK_NOWAIT</a>
flag or lock timers were configured, could not be granted before the
wait-time expired.</p>
<p>Additionally, DbLockNotGrantedException is thrown when a Berkeley DB
Concurrent Data Store database environment configured for lock timeouts
was unable to grant a lock in the allowed time.</p>
<p>Additionally, DbLockNotGrantedException is thrown when lock or
transaction timeouts have been configured, a database operation has
timed out, and the <a href="../api_cxx/env_set_flags.html#DB_TIME_NOTGRANTED">DB_TIME_NOTGRANTED</a> configuration flag has
been specified.</p>
<p>The <a href="../api_cxx/except_class.html">DbException</a> errno value is set to DB_LOCKNOTGRANTED.</p>
<p>The <b>get_op</b> method returns 0 when <a href="../api_cxx/lock_get.html">DbEnv::lock_get</a> was called,
and returns the <b>op</b> for the failed DB_LOCKREQ when
<a href="../api_cxx/lock_vec.html">DbEnv::lock_vec</a> was called.</p>
<p>The <b>get_mode</b> method returns the <b>mode</b> parameter when
<a href="../api_cxx/lock_get.html">DbEnv::lock_get</a> was called, and returns the <b>mode</b> for the failed
DB_LOCKREQ when <a href="../api_cxx/lock_vec.html">DbEnv::lock_vec</a> was called.</p>
<p>The <b>get_obj</b> method returns the <b>mode</b> parameter when
returns the <b>object</b> parameter when <a href="../api_cxx/lock_get.html">DbEnv::lock_get</a> was called,
and returns the <b>object</b> for the failed DB_LOCKREQ when
<a href="../api_cxx/lock_vec.html">DbEnv::lock_vec</a> was called.
The <a href="../api_cxx/dbt_class.html">Dbt</a> pointer may or may not refer to valid memory, depending on
whether the <a href="../api_cxx/dbt_class.html">Dbt</a> used in the call to the failed <a href="../api_cxx/lock_get.html">DbEnv::lock_get</a> or
<a href="../api_cxx/lock_vec.html">DbEnv::lock_vec</a> method is still in scope and has not been deleted.</p>
<p>The <b>get_lock</b> method returns NULL when <a href="../api_cxx/lock_get.html">DbEnv::lock_get</a> was
called, and returns the <b>lock</b> in the failed DB_LOCKREQ
when <a href="../api_cxx/lock_vec.html">DbEnv::lock_vec</a> was called.</p>
<p>The <b>get_index</b> method returns -1 when <a href="../api_cxx/lock_get.html">DbEnv::lock_get</a> was
called, and returns the index of the failed DB_LOCKREQ when
<a href="../api_cxx/lock_vec.html">DbEnv::lock_vec</a> was called.</p>
