synchronizing-structure

This class was added by a patch released in July, 2009. This macro will not be defined if that patch has not been installed. See sys:update-allegro for information on downloading patches.

This structure class is used as a base structure when instances of a structure class are to be locked with the with-locked-structure macro.

Example usage

	 (defstruct (my-lockable-thing
       		      (:include synchronizing-structure)
		      ...)
	   ...)
	 ...
	 (setq thing (make-my-lockable-thing ...))
	 ...
	 (with-locked-structure (thing)
           ...)

See smp.htm and multiprocessing.htm for more information on this macro and on multiprocessing.
