Description: DB_ENV-&gt;set_lk_conflicts
Set the locking conflicts matrix.
If DB_ENV-&gt;set_lk_conflicts is never called, a standard conflicts
array is used; see <a href="../../db4-devel-4.7.25/ref/lock/stdmode.html">Standard Lock
Modes</a> for more information.
The DB_ENV-&gt;set_lk_conflicts method configures a database environment, not only operations
performed using the specified <a href="../../db4-devel-4.7.25/api_c/env_class.html">DB_ENV</a> handle.
The DB_ENV-&gt;set_lk_conflicts method may not be called after the <a href="../../db4-devel-4.7.25/api_c/env_open.html">DB_ENV-&gt;open</a> method is
called.
If the database environment already exists when
<a href="../../db4-devel-4.7.25/api_c/env_open.html">DB_ENV-&gt;open</a> is called, the information specified to DB_ENV-&gt;set_lk_conflicts
will be ignored.

The DB_ENV-&gt;set_lk_conflicts method
returns a non-zero error value on failure
and 0 on success.

Parameters 
 conflicts<ul compact><li>The conflicts parameter is the new locking conflicts matrix.
The conflicts parameter is an nmodes by nmodes
array. A non-0 value for the array element indicates that
requested_mode and held_mode conflict:
<blockquote><pre>conflicts[requested_mode][held_mode]</pre></blockquote>
The not-granted mode must be represented by 0.</ul>
 nmodes<ul compact><li>The nmodes parameter is the size of the lock conflicts matrix.</ul>
 
 Errors
The DB_ENV-&gt;set_lk_conflicts method
may fail and return one of the following non-zero errors:
 
EINVAL<ul compact><li>If the method was called after <a href="../../db4-devel-4.7.25/api_c/env_open.html">DB_ENV-&gt;open</a> was called; or if an
invalid flag value or parameter was specified.</ul>
 
 
ENOMEM<ul compact><li>The conflicts array could not be copied.</ul>
 
<hr size=1 noshade>
Description: dbenv_get_lk_conflicts
The DB_ENV-&gt;get_lk_conflicts method returns the current conflicts array.
The DB_ENV-&gt;get_lk_conflicts method may be called at any time during the life of the
application.
The DB_ENV-&gt;get_lk_conflicts method
returns a non-zero error value on failure
and 0 on success.

Parameters 
 lk_conflictsp<ul compact><li>The lk_conflictsp parameter references memory into which
a pointer to the current conflicts array is copied.</ul> 
 lk_modesp<ul compact><li>The lk_modesp parameter references memory into which
 the size of the current conflicts array is copied.</ul>
