unlink0

Remove a temporary file while its filehandle is still open.

תקציר

unlink0($fh, $path) or die "unlink0: $!";

מה מוחזר

Integer 1 on success. The directory entry is removed; reads and writes on $fh continue to work, and the blocks are released when $fh is finally closed.

דוגמאות

use File::Temp qw/ tempfile unlink0 /;
my ($fh, $path) = tempfile();
unlink0($fh, $path);

## $path is gone, but $fh is still usable

מקרי קצה

• If $File::Temp::KEEP_ALL is true the function returns 1 without unlinking.

• Fewer than two arguments: no-op, returns 1.

הבדלים מן ה-upstream

• Upstream performs a full stat/fstat comparison before unlinking to detect races and symlink tricks. This implementation unlinks by path without that check. Callers who need the stat-equality guarantee should validate the handle themselves. Covered by t/81-xs-native/File-Temp/*.t.
