funwrap

Arguments: primary-function indicator

Returns the primary function object, after removing the indicated fwrapper. Note that it is not an error to funwrap a primary-function that is not fwrapped, nor is it an error to specify an indicator on which there is no fwrapper; such requests are silently ignored. It is, however, necessary that the primary-function be either a symbol fbound to a function object or else a function object itself.

See fwrappers-and-advice.htm for information of fwrapping functions (and on the older, deprecated advice facility).
