<dd><p><strong>Note</strong> This method is not available on Windows as it does not
support the fork system call.</p>
<p>SQLite does not allow the use of database connections across <a class="reference external" href="http://en.wikipedia.org/wiki/Fork_(operating_system)">forked</a> processes
(see the <a class="reference external" href="https://sqlite.org/faq.html#q6">SQLite FAQ Q6</a>).
(Forking creates a child process that is a duplicate of the parent
including the state of all data structures in the program.  If you
do this to SQLite then parent and child would both consider
themselves owners of open databases and silently corrupt each
other&#8217;s work and interfere with each other&#8217;s locks.)</p>
<p>One example of how you may end up using fork is if you use the
<a class="reference external" href="http://docs.python.org/library/multiprocessing.html">multiprocessing module</a> which uses
fork to make child processes.</p>
<p>If you do use fork or multiprocessing on a platform that supports
fork then you <strong>must</strong> ensure database connections and their objects
(cursors, backup, blobs etc) are not used in the parent process, or
are all closed before calling fork or starting a <a class="reference external" href="http://docs.python.org/library/multiprocessing.html#process-and-exceptions">Process</a>.
(Note you must call close to ensure the underlying SQLite objects
are closed.  It is also a good idea to call <a class="reference external" href="http://docs.python.org/library/gc.html#gc.collect">gc.collect(2)</a> to ensure
anything you may have missed is also deallocated.)</p>
<p>Once you run this method, extra checking code is inserted into
SQLite&#8217;s mutex operations (at a very small performance penalty) that
verifies objects are not used across processes.  You will get a
<a class="reference internal" href="exceptions.html#apsw.ForkingViolationError" title="apsw.ForkingViolationError"><code class="xref py py-exc docutils literal"><span class="pre">ForkingViolationError</span></code></a> if you do so.  Note that due to the way
Python&#8217;s internals work, the exception will be delivered to
<cite>sys.excepthook</cite> in addition to the normal exception mechanisms and
may be reported by Python after the line where the issue actually
arose.  (Destructors of objects you didn&#8217;t close also run between
lines.)</p>
<p>You should only call this method as the first line after importing
APSW, as it has to shutdown and re-initialize SQLite.  If you have
any SQLite objects already allocated when calling the method then
the program will later crash.  The recommended use is to use the fork
checking as part of your test suite.</p>

<p>SQLite has <a class="reference external" href="https://sqlite.org/c3ref/constlist.html">many constants</a> used in various
interfaces.  To use a constant such as <code class="xref py py-const docutils literal"><span class="pre">SQLITE_OK</span></code>, just
use <code class="docutils literal"><span class="pre">apsw.SQLITE_OK</span></code>.</p>
<p>The same values can be used in different contexts. For example
<code class="xref py py-const docutils literal"><span class="pre">SQLITE_OK</span></code> and <code class="xref py py-const docutils literal"><span class="pre">SQLITE_CREATE_INDEX</span></code> both have a value
of zero. For each group of constants there is also a mapping (dict)
available that you can supply a string to and get the corresponding
numeric value, or supply a numeric value and get the corresponding
string. These can help improve diagnostics/logging, calling other
modules etc. For example:</p>
