in reply to how to unpack a C struct with length array preceding data array

If you really want to do it in one unpack you can...

use strict; use warnings; use Data::Dumper; my @arr = unpack('(W W @0Wx/a @1W@0Wx/x/a)', "\005\006Hello World"); print Dumper(\@arr);

Which produces:

$VAR1 = [ 5, 6, 'Hello', ' World' ];

But I would never do that, except to prove that I could.

[marioroy]: Hello all. After several attempts, am able to move forward and will soon release a Parallel:: ForkManager compatible MCE::Hobo:: Manager, also MCE::Hobo::Simple, and refactored MCE::Hobo engine supporting multiple instances. Wait works beautifully.
[marioroy]: MCE::Shared has been refined that it allows sharing Tie::File and hash objects containing {fh} key.
[marioroy]: It's taken so long to take Hobo to a new level. Threads-like and Parallel:: ForkManager management capaiblities.
[marioroy]: This will complete the 4 years in the making and likely time to move on to something els.
[marioroy]: s/els/else.
[marioroy]: The MCE::Hobo::Pool module will come later.
