# NAME

lock - get a thread lock on a variable, subroutine, or method

# SYNOPSIS

lock THING

# DESCRIPTION

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 the threads manpage.
