NAME

File::Flock - file locking with flock

SYNOPSIS

use File::Flock;

lock($filename);

lock($filename, 'shared');

lock($filename, undef, 'nonblocking');

lock($filename, 'shared', 'nonblocking');

unlock($filename);

my $lock = new File::Flock '/somefile';

DESCRIPTION

Lock files using the flock() call. If the file to be locked does not exist, then the file is created. If the file was created then it will be removed when it is unlocked assuming it's still an empty file.

Locks can be created by new'ing a File::Flock object. Such locks are automatically removed when the object goes out of scope. The unlock() method may also be used.
