Attribute the value bound to var->bound.

Default functions associated to the chosen protocol.

Parameters

func_fpi

inverse of the partial differential of f (f prime inverse, (f')^{-1})

Set default functions to the ones passed as parameters. This is a polymorphism in C pure, enjoy the roots of programming.
