basic-lock

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 is a simple extension of synchronizing-structure, adding a name slot. Instances can be allocated and used as standalone locks in the with-locked-structure macro.

Example usage

	 (defvar xlock (make-basic-lock :name "xwidget lock"))
	 ...
	 (with-locked-structure (xlock)
	    ...)

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