NAME

PerlIO::excl - Creates a file only if it doesn't exist

SYNOPSIS

        open my $io,  '+<:excl', 'foo.txt';

DESCRIPTION

PerlIO::excl appends O_EXCL to the open flags.

When you'd like to create a file only if it doesn't exist before, you can use the :excl layer.

This is a pseudo layer that doesn't be pushed on the layer stack.
