fwrap-order

Arguments: primary-function &key outer inner

Returns the fwrapper property list, after possibly modifying the ordering of the indicated fwrappers. If either or both of outer or inner are specified, then they should be indicators for which the primary-function has an fwrapper. These indicator/fwrapper pairs are moved from the order they are currently in to either the outermost or innermost position depending on which keyword was selected. Both outer and inner may be selected in the same call, but they must not refer to the same indicator.

There is no way to specify the order in one action, but repeated calls to fwrap-order can result in any desired order.

Note: The order of fwrappers is determined before the point of call to the primary function. The behavior is not defined (as to the number and ordering of fwrappers called) if the order is changed while the fwrappers are being executed.

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