mktemp#
Fill in the trailing Xs of a template and return the resulting filename — does not create the file.
Synopsis#
my $name = mktemp('/tmp/dataXXXXXX');
What you get back#
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.
Examples#
use File::Temp qw/ mktemp /;
my $name = mktemp('/var/tmp/snapXXXXXXXX');
Edge cases#
Template with fewer than four trailing
Xs: croaks.Wrong arg count: croaks with a usage message.
Unsafe against racing attackers — prefer
tempfile.
Differences from upstream#
Fully compatible with upstream File::Temp 0.2312.

tempfile— race-safe replacement.mkstemp— same idea, but also creates and opens the file.tempnam—dir + prefixvariant.
