I have made a package wrapper for Net::FTP the purpose is for error code checking.

The package declares "our ftpObj", can you tell me what happens if all threads use the ftpObj, even though they make their own connections will I get conflicts because of the variable is declared as 'our'.

Unless you explicitly share a varible, each thread will have it's own copy.

But, if you assign an object to a variable, before you spawn a thread, the new thread will usually not be able to use its copy successfully. It is quite hard to advise you without seeing your code.

I have 2 files

1. Package wrapper for NET::FTP (error checking)
2. main code that creates threads and self master.
<code>
# File 1
package myFtp;
use Net::FTP;
use Net::Cmd;
our @ftpObj;
our @ftpList = ();
our @code;

sub Connect
{
    my ($ftpServer, $ftpTimeout, $connection_type) = @_;

    #debug ("Trying -> ", $ftpServer);
    $ftpObj = Net::FTP->new($ftpServer, Timeout => $ftpTimeout, Passiv
+e => $connection_type);
    return;
}
#other functions....

use SPFtp qw (Connect Login PrepareLsFtpList deleteFile GetFile GetFil

Here is my question?

Will $ftpObj Variable get screwed up? I am pretty sure it will.
