NAME

Ubic::AtomicFile - atomic file operations

VERSION

version 1.55

SYNOPSIS

use Ubic::AtomicFile;

Ubic::AtomicFile::store("blah\n" => "/var/lib/blah");

# store but don't sync content to disk
Ubic::AtomicFile::store("blah\n" => "/var/lib/blah", { sync => 0 });

FUNCTIONS

store($data, $file)

store($data, $file, $options)

Store $data into $file atomically. Temporary $file.new will be created and then renamed to $file.

If sync flag is set and false in $options hash then data will not be synced on disk before file is renamed (should be faster, but you can lose your data - see comments in code).
