Is there anyway I can get this to work? Because I have passed around this $mem_file in my script and would like to use it instead of having to re-read the actual file. If i need to elaborate any more please let me know :)

EDIT: I will go ahead and elaborate a little more. when I pass $mem_file to the sub and try to open it like this:

 
stat_check($mem_file);

sub stat_check{
    my ($mem_file) = @_;
    
    my $fh    = MCE::Shared->handle( "<:raw", \$mem_file );
    ....rest of threaded function...
}

I get error:

Not a GLOB reference at C:/Perl/site/lib/MCE/Shared/Server.pm line 203
+6, <__ANONIO__> line 3.

If i try:

stat_check($mem_file);

sub stat_check{
    my ($mem_file) = @_;
    
    my $fh    = MCE::Shared->handle( "<:raw", $mem_file );
    ....rest of threaded function...
}

Unfortunately, MCE::Shared does not support a handle obtained by opening a scalar reference. Shared file handles have a real file descriptor.

Ok, I was just wondering, because the file has already been read once and seems like it would be even faster if it could act on the scalar. Thanks anyway :)
