Harry,
> Look at the script. It is actually doing an IGNORE and a block.
You're right.
Assuming the code is correct (I don't know Perl all that well) then
this would mean that SIGCONT can't be blocked -- something that I've
not been able to find in the UNIX standard.
I don't like depending on undocumented behavior -- not for something
that needs to run on any UNIX-conforming system. Do you see anything
wrong with making decoders their own process-group leaders?
Regards,
Steve Emmerson
