mktemp

Fill in the trailing Xs of a template and return the resulting filename - does not create the file.

תקציר

my $name = mktemp('/tmp/dataXXXXXX');

מה מוחזר

A candidate filename string with random characters substituted for the trailing Xs. No file is created; the caller must open it themselves and accept the race between naming and opening.

דוגמאות

use File::Temp qw/ mktemp /;
my $name = mktemp('/var/tmp/snapXXXXXXXX');

מקרי קצה

• Template with fewer than four trailing Xs: croaks.

• Wrong arg count: croaks with a usage message.

• Unsafe against racing attackers - prefer tempfile.

הבדלים מן ה-upstream

Fully compatible with upstream File::Temp 0.2312.
