Win32::Process - Create and manipulate processes.

$ProcessObj->Wait(INFINITE);
DESCRIPTION
This module provides access to the process control functions in the
Win32 API.
METHODS
Win32::Process::Create($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)
$curdir working dir of new process
Returns non-zero on success, 0 on failure.
Win32::Process::Open($obj,$pid,$iflags)
Creates a handle Perl can use to an existing process as
identified by $pid. The $iflags is the inherit flag that is
passed to OpenProcess. Currently Win32::Process objects
created using Win32::Process::Open cannot Suspend or Resume the
process. All other calls should work.
Win32::Process::Open returns non-zero on success, 0 on failure.
Win32::Process::KillProcess($pid, $exitcode)
Terminates any process identified by $pid. $exitcode will be
set to the exit code of the process.
$ProcessObj->Suspend()
Suspend the process associated with the $ProcessObj.
$ProcessObj->Resume()
Resume a suspended process.
$ProcessObj->Kill($exitcode)
Kill the associated process, have it terminate with exit code
$ExitCode.
$ProcessObj->GetPriorityClass($class)
Get the priority class of the process.
$ProcessObj->SetPriorityClass($class)
Set the priority class of the process (see exported values
below for options).
$ProcessObj->GetProcessAffinityMask($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.
$ProcessObj->SetProcessAffinityMask($processAffinityMask)
Set the process affinity mask. Only available on Windows NT.
$ProcessObj->GetExitCode($exitcode)
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.
$ProcessObj->Wait($timeout)
Wait for the process to die. $timeout should be specified in
milliseconds. To wait forever, specify the constant
"INFINITE".
$ProcessObj->GetProcessID()
Returns the Process ID.
Win32::Process::GetCurrentProcessID()
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 GetCurrentProcessID() returns the
windows PID as needed for all the Win32::Process functions.
