<p>This module provides access to the process control functions in the
Win32 API.</p>

<h1><a name="methods">METHODS</a></h1>
<dl>
<dt><strong><a name="item_create">Win32::Process::Create($obj,$appname,$cmdline,$iflags,$cflags,$curdir)</a></strong>

<dd>
<p>Creates a new process.</p>
</dd>
<dd>
<pre>
    Args:</pre>
</dd>
<dd>
<pre>
        $obj            container for process object
        $appname        full path name of executable module
        $cmdline        command line args
        $iflags         flag: inherit calling processes handles or not
        $cflags         flags for creation (see exported vars below)
        $curdir         working dir of new process</pre>
</dd>
<dd>
<p>Returns non-zero on success, 0 on failure.</p>
</dd>
</li>
<dt><strong><a name="item_open">Win32::Process::Open($obj,$pid,$iflags)</a></strong>

<dd>
<p>Creates a handle Perl can use to an existing process as identified by $pid.
The $iflags is the inherit flag that is passed to OpenProcess.  Currently
Win32::Process objects created using Win32::Process::Open cannot Suspend
or Resume the process.  All other calls should work.</p>
</dd>
<dd>
<p>Win32::Process::Open returns non-zero on success, 0 on failure.</p>
</dd>
</li>
<dt><strong><a name="item_killprocess">Win32::Process::KillProcess($pid, $exitcode)</a></strong>

<dd>
<p>Terminates any process identified by $pid.  $exitcode will be set to
the exit code of the process.</p>
</dd>
</li>
<dt><strong><a name="item_suspend">$ProcessObj-&gt;<code>Suspend()</code></a></strong>

<dd>
<p>Suspend the process associated with the $ProcessObj.</p>
</dd>
</li>
<dt><strong><a name="item_resume">$ProcessObj-&gt;<code>Resume()</code></a></strong>

<dd>
<p>Resume a suspended process.</p>
</dd>
</li>
<dt><strong><a name="item_kill">$ProcessObj-&gt;<code>Kill($exitcode)</code></a></strong>

<dd>
<p>Kill the associated process, have it terminate with exit code $ExitCode.</p>
</dd>
</li>
<dt><strong><a name="item_getpriorityclass">$ProcessObj-&gt;<code>GetPriorityClass($class)</code></a></strong>

<dd>
<p>Get the priority class of the process.</p>
</dd>
</li>
<dt><strong><a name="item_setpriorityclass">$ProcessObj-&gt;<code>SetPriorityClass($class)</code></a></strong>

<dd>
<p>Set the priority class of the process (see exported values below for
options).</p>
</dd>
</li>
<dt><strong><a name="item_getprocessaffinitymask">$ProcessObj-&gt;GetProcessAffinityMask($processAffinityMask, $systemAffinityMask)</a></strong>

<dd>
<p>Get the process affinity mask.  This is a bitvector in which each bit
represents the processors that a process is allowed to run on.</p>
</dd>
</li>
<dt><strong><a name="item_setprocessaffinitymask">$ProcessObj-&gt;<code>SetProcessAffinityMask($processAffinityMask)</code></a></strong>

<dd>
<p>Set the process affinity mask.  Only available on Windows NT.</p>
</dd>
</li>
<dt><strong><a name="item_getexitcode">$ProcessObj-&gt;<code>GetExitCode($exitcode)</code></a></strong>

<dd>
<p>Retrieve the exitcode of the process. Will return STILL_ACTIVE if the
process is still running. The STILL_ACTIVE constant is only exported
by explicit request.</p>
</dd>
</li>
<dt><strong><a name="item_wait">$ProcessObj-&gt;<code>Wait($timeout)</code></a></strong>

<dd>
<p>Wait for the process to die.  $timeout should be specified in milliseconds.
To wait forever, specify the constant <code>INFINITE</code>.</p>
</dd>
</li>
<dt><strong><a name="item_getprocessid">$ProcessObj-&gt;<code>GetProcessID()</code></a></strong>

<dd>
<p>Returns the Process ID.</p>
</dd>
</li>
<dt><strong><a name="item_getcurrentprocessid">Win32::Process::GetCurrentProcessID()</a></strong>

<dd>
<p>Returns the current process ID, which is the same as $$. But not on cygwin,
where $$ is the cygwin-internal PID and not the windows PID.
On cygwin <a href="#item_getcurrentprocessid"><code>GetCurrentProcessID()</code></a> returns the windows PID as needed for all
the Win32::Process functions.</p>
</dd>
</li>
</dl>
