NAME

File::Open::NoCache::ReadOnly - Open a file and clear the cache afterward

VERSION

Version 0.01

SUBROUTINES/METHODS

new

Open a file and flush the cache afterwards. One use case is building a large database from smaller files that are only read in once. Once the file has been used it's a waste of RAM to keep it in cache.

    use File::Open::NoCache::ReadOnly;
    my $fh = File::Open::NoCache::ReadOnly->new('/etc/passwd');

fd

Returns the file descriptor of the file

    my $fd = $fh->fd();
    my $line = <$fd>;
