unlink_on_destroy#

Toggle or query whether a File::Temp object unlinks its file when destroyed.

Σύνοψη#

my $flag = $tmp->unlink_on_destroy;         # getter
$tmp->unlink_on_destroy(0);                 # keep the file
$tmp->unlink_on_destroy(1);                 # remove on destruction

Τι επιστρέφεται#

The new (or current) flag value as an integer: 1 if the file will be removed when the object is destroyed, 0 otherwise.

Παραδείγματα#

my $tmp = File::Temp->new;
$tmp->unlink_on_destroy(0);

## $tmp->filename survives after $tmp goes out of scope

Οριακές περιπτώσεις#

Called on something that is not a File::Temp object: returns 1 without touching state.
Setting to a true value on an object whose file is no longer tracked does not re-register it.

Διαφορές από το upstream#

The flag is stored in an internal map rather than the blessed glob’s hash slot. Code that pokes at %{*$fh} directly will not observe the flag; use the method. Covered by t/81-xs-native/File-Temp/*.t.
