DBENV->set_lk_max_locks(DB_ENV *dbenv, u_int32_t max);
</pre></h3>
<h1>Description</h1>
<p>Set the maximum number of locks supported by the Berkeley DB lock subsystem.
This value is used by <a href="../api_c/env_open.html">DBENV->open</a> to estimate how much space to
allocate for various lock-table data structures. For specific
information on configuring the size of the lock subsystem, see
<a href="../ref/lock/max.html">Configuring locking: sizing the system</a>.
<p>The DBENV->set_lk_max_locks interface may only be used to configure Berkeley DB before
the <a href="../api_c/env_open.html">DBENV->open</a> interface is called.
<p>The DBENV->set_lk_max_locks function returns a non-zero error value on failure and 0 on success.
<p>The database environment's maximum number of locks may also be set using the environment's
<b>DB_CONFIG</b> file. The syntax of the entry in that file is a
single line with the string "set_lk_max_locks", one or more whitespace characters,
and the number of locks. Because the <b>DB_CONFIG</b> file is read when the database
environment is opened, it will silently overrule configuration done
before that time.
<h1>Errors</h1>
<p><dl compact>
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
<p>Called after <a href="../api_c/env_open.html">DBENV->open</a> was called.
