<h1>Description</h1>
|
|
<p>Set the locking conflicts matrix.
|
|
The <b>conflicts</b> argument
|
|
is an <b>nmodes</b> by <b>nmodes</b> array.
|
|
A non-0 value for the array element:
|
|
<p><blockquote><pre>conflicts[requested_mode][held_mode]</pre></blockquote>
|
|
<p>indicates that requested_mode and held_mode conflict. The
|
|
<i>not-granted</i> mode must be represented by 0.
|
|
<p>If no <b>conflicts</b> value is specified, the conflicts array
|
|
<b>db_rw_conflicts</b> is used; see <a href="../ref/lock/stdmode.html">Standard Lock Modes</a> for a description of that array.
|
|
<p>The DbEnv::set_lk_conflicts 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_lk_conflicts 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.
|
|
