Attempt to use Win32::Process`::Open( my $handle, $pid, 0 );` to obtain a handle to the running process. If the call succeeds, it is still running. You could also avoid having to poll the process by using `$handle->Wait( $timeoutms );` to wait until it ends (or the timeout occurs) and then `$handle->Kill( $exitcode )` to kill it if it runs too long.

`qx{pslist.exe $pid}`? copy/paste win32_kill into Inline::C? Win32::Process::Info?	[reply]

An alternative to pslist would be wmic, which comes with Windows (at least from XP and up). However, I wanted to avoid a solution where I had to shell out for this, because it means that I need to filter out the PIDs for the pslist/wmic process (and, perhaps, an interim command shell process). I wanted to avoid Win32::Process::Info too, because of the many problems pointed out in its documentation, but after all, this was the solution I ended up with, because the alternatives were even less attractive. Actually, I personally would prefer upgrading Perl to a version where `kill` works as documented, but this is not feasible at the moment... -- Ronald Fischer <ynnor@mm.st>	[reply] [d/l] [select]
