This simple locking scheme is not based on any file locking system calls such as "flock()" or "lockf()" but rather relies on basic file system primitives and properties, such as the atomicity of the "write()" system call. It is not meant to be exempt...

Provide locking/mutex mechanism under (at least) UNIX and Win32 that will function correctly even in networked/NFS environments. It is based on the concept that if two processes each connect to the same host via ftp and try to create the same directo...

lock() Attempts to acquire lock. Returns pid if successful. Returns undef otherwise....

lock( file, epoch => start, duration => seconds ) Writes time into the file....

Lazy::Lockfile is a module designed for simple locking through the use of lockfiles, requiring very little effort on the part of the developer. Once the object is instanced, the lock will be held as long as object exists. When the object is destroyed...

"IPC::Lockfile" is a module for use with Perl programs when you only want one instance of the script to run at a time. It uses "flock" and should work if run on an OS that supports "flock" (e.g. Linux, BSD, OSX and Windows)....

This module provides convenience functions for using a lockfile to coordinate multi-process activities. While basically just a thin wrapper for Paranoid::IO functions it removes the small tedium of having to perform the multiple opens required to ens...
