man perlfunc
flock FILEHANDLE,OPERATION
Calls flock(2), or an emulation of it, on FILEHANDLE.Returns true for success,
false on failure. Produces a fatal error if used on a machine that doesn't implement
flock(2), fcntl(2) locking, or lockf(3). flock is Perl's portable file locking interface,
although it locks only entire files, not records.
