Win32::Process - Create and manipulate processes.
=head1 SYNOPSIS
use Win32::Process;
use Win32;
sub ErrorReport{
print Win32::FormatMessage( Win32::GetLastError() );
}
Win32::Process::Create($ProcessObj,
"D:\\winnt35\\system32\\notepad.exe",

$ProcessObj->Wait(INFINITE);
=head1 DESCRIPTION
This module provides access to the process control functions in the
Win32 API.
=head1 METHODS
=over 8
=item Win32::Process::Create($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.
