• lock THING

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

  The value returned is the scalar itself, if the argument is a scalar, or areference, if the argument is a hash, array or subroutine.

  lock() is a "weak keyword" : this means that if you've defined a functionby this name (before any calls to it), that function will be calledinstead. If you are not under use threads::shared this does nothing.See threads::shared.
