Perl 5 version 10.1 documentation


  • lock THING

    This function places an advisory lock on a shared variable, or referenced object contained in THING until the lock goes out of scope.

    lock() is a "weak keyword" : this means that if you've defined a function by this name (before any calls to it), that function will be called instead. (However, if you've said use threads , lock() is always a keyword.) See threads.
