Thanks a lot! BrowserUk. You are really great!

I'm sorry in fact there are some typos such as exported function names and missing the "1;" at the end of test.pm, etc. I should've double check my post...

But I am really weak on this part. The syntax to specify the subroutine-name in threads->create is confusing to me. And I guess maybe the latest release has addressed this problem (passing subroutine-name as string instead of code-ref). I have another question about code ref. In fact, I want my code to deal with unknown subroutine name beforehand. Instead, the name may be given in a parameter file in XML like the following:

<thread>
    <module>module_name</module>
    <subroutine>subroutine_name</subroutine>
</thread>

A script reads the file and put modulename in var "$module" and subroutinename in "$subroutine". Then, what is the correct syntax to create a thread for "$subroutine"? I guess I have to use Module::Load to dynamically load a module first and then call threads->create to run a thread for a subroutine. Will this cause some problem?

Thanks!

And I rewrite 2nd part as follows. Please help. Thanks!

"Scalar leaked:1" error.
It is for simplicity that bareword "argument" is used in place of any type of variable.
_test.pl_

use threads;
use test;
 
my $thread=threads->create('forthread', (argument));
$thread->join();
exit(0);
[download]

-test.pm_

package test;
 
require Exporter;
                               
our @ISA        =qw(Exporter);
our @EXPORT     =qw(forthread);
our @VERSION    =1.0;
 
sub forthread{
        my (argument)=@_;
my $thread=threads->create('another', (argument));
$thread->join();
        return 0;
} #forthread

sub another{
return 0;
} #another

NOTE: the error is reported when "argument" is one of the following:
- reference to scalar
- reference to array
- reference to hash
- hash
