File::Flock(3) User Contributed Perl Documentation File::Flock(3)NAMEFile::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 $lock = new File::Flock '/somefile';
lock_rename($oldfilename, $newfilename)
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.
lock_rename() is used to tell File::Flock when a file has been renamed
(and thus the internal locking data that is stored based on the
filename should be moved to a new name). unlock() the new name rather
than the original name.
LICENSEFile::Flock may be used/modified/distibuted on the same terms as perl
itself.
