unadvise

Arguments: &optional fspec class name

Starting in Allegro CL release 6.0, the new fwrapper facility, described in fwrappers-and-advice.htm, replaces the advice facility, and continued use of the advice facility is deprecated.

This macro removes advice with the class and name specified from the function (or macro) specified by fspec. Any of the three arguments may be nil. nil works like a wildcard: all advice specified by the other arguments is removed. All of the arguments default to nil.

It is an error to unadvise a function named by a symbol which has been fmakunbound. Doing so may result in the symbol again having a function definition.

Note: unadvise called without arguments removes all advice from all functions and macros.

See also fwrappers-and-advice.htm for general information on the new fwrapper facility and the older, now deprecated, advice facility in Allegro CL.
