=head1  DESCRIPTION

This module provides access to the process control functions in the
Win32 API.

=head1 METHODS

=over 8

=item Win32::Process::Create($obj,$appname,$cmdline,$iflags,$cflags,$curdir)

Creates a new process.

    Args:

	$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

Returns non-zero on success, 0 on failure.

=item Win32::Process::Open($obj,$pid,$iflags)

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.

Win32::Process::Open returns non-zero on success, 0 on failure.

=item Win32::Process::KillProcess($pid, $exitcode)

Terminates any process identified by $pid.  $exitcode will be set to
the exit code of the process.

=item $ProcessObj->Suspend()

Suspend the process associated with the $ProcessObj.

=item $ProcessObj->Resume()

Resume a suspended process.

=item $ProcessObj->Kill( $exitcode )

Kill the associated process, have it terminate with exit code $ExitCode.

=item $ProcessObj->GetPriorityClass($class)

Get the priority class of the process.

=item $ProcessObj->SetPriorityClass( $class )

Set the priority class of the process (see exported values below for
options).

=item $ProcessObj->GetProcessAffinitymask( $processAffinityMask, $systemAffinitymask)

Get the process affinity mask.  This is a bitvector in which each bit
represents the processors that a process is allowed to run on.

=item $ProcessObj->SetProcessAffinitymask( $processAffinityMask )

Set the process affinity mask.  Only available on Windows NT.

=item $ProcessObj->GetExitCode( $exitcode )

Retrieve the exitcode of the process.

=item $ProcessObj->Wait($timeout)

Wait for the process to die.  $timeout should be specified in milliseconds.
To wait forever, specify the constant C<INFINITE>.

=item $ProcessObj->GetProcessID()

Returns the Process ID.
