Dear monks!
I have written a wrapper for shared memory operations around IPC::Shareable. This sub ties the given vars (code is 'work in progress', suggestions welcome).
sub initial_tie {
my ($aref, $what, $cont) = @_;
my @do = @$aref;
if (defined $what) {
$cont && (undef $cont) || ($cont = 1);
@do = splice(@do, $what, $cont)
}
while (@do) {
my $data = shift @do;
my $cmd;
$cmd = "tie($data->[0], 'IPC::Shareable',
{key => '$data->[1]',
create => $data->[2],
mode => $data->[3],
size => $data->[4],
destroy => $data->[5]});";
$result = eval $cmd;
if ($data->[6]++ > 3) {
&Log("*** initial_tie giving up on $data->[0] ***");
} elsif (not defined $result) {
# create if necessary
$data->[2] = 1;
push(@do, $data);
}
}
}
Unfortunately, this sub is in MyModule::Shmem, which is very restrictive about export (@EXPORT_OK used instead of @EXPORT). The vars to be tied in are not known at compile time.
Now for the question: How do I make the tied variable visible outside of MyModule::Shmem?
Rgds.
