Problem sharing hash across multiple threads
|
Can't Post
|
|
Writing a Perl Tcl/Tk GUI application. Need to share a hash across multiple perl threads. In particular, this hash is the TixGrid. When I print out the address of the instance of the TixGrid outside of the thread, I get one value, and I print out the address of the instance of the TixGrid inside the thread I get another address. Then when I try to set a value of the TixGrid within the thread the program crashes. The TixGrid instance is stored in a parent hash, like $mydata->{mytixgrid},
and I do declare the mydata shared via:
my %mydata : shared;
I also did try to declare $mydata->{} shared via:
share($mydata->{});
but the perl interpreter did not recognize the share function, eventhough I have:
use Threads;
use Threads::Shared;
Any help would be appreciated. Also, I can explain more about the structure and purpose of this program and my motivation for needing to share a TixGrid across multiple threads if interested.
Thanks,
Michael
