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.

$ProcessObj->Wait($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.
