If you are using -use- to load the modules, they _will_ have been loaded
already. For example:
use threads;
my $thread = threads->new( 'doDIBstuff' );
sub doDBIstuff {
use DBI parameters; # executed during compile time
}
_will_ have loaded DBI when the threads starts. This is because -use- is
executed in compilation (BEGIN). From perldoc -f use:
"It is exactly equivalent to BEGIN { require Module; import Module LIST; }..."
If you really want to load the DBI module inside the thread only, you
should do:
sub doDBIstuff {
required DBI; # executed during runtime
DBI->import( parameters ); # executed during runtime
}
Hope this helps...
