win32 forking and threads

Need Help??

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

hi. i have an ftp program that will automatically upload and download from a site every hour. i have a win32::gui frontend for it so when it starts uploading or downloading the gui effectively freezes until its finished.

in the upload and download subroutine i tried putting in

if ($pid = fork) {
#upload and download
} else {
    print "error forking: $!\n";
}
[download]

but when i try to run it i get an error saying bizarre svtype 30.

so then i tried using threads but i'm told that this perl was built for use with ithreads. and i read perldoc Thread which says the same thing, so then how do i use ithreads?

i'm running activestate perl 5.6.1.631 and 5.6.1 compiled with the USE_MULTI, USE_ITHREADS and USE_IMP_SYS flags on windows 98se. it does the same thing on both builds.

thanx in advance

on win(2000) I tent not to use "fork" but "Win32::Process::Create" in my experience that works great ... perhaps it will also work for you ---- NaSe :x	[reply]

FYI fork on Win32 is emulated using ithreads (see perlfork). So you are using them already (though implicitly). -- Ilya Martynov (http://martynov.org/)	[reply]

which version of Win32::GUI are you using? version 0.0.665 should play fair with forks. cheers, Aldo `__END__ $_=q,just perl,,s, , another ,,s,$, hacker,,print;` [download]	[reply] [d/l]
