Instances of this class represent external (non-Smalltalk) functions.
(Obsolete) Custom Functions:
- This class also provides access to custom functions.
- These custom functions enable you to call c functions
- even if no stc compiler is available (they are kind of what user-primitives are in ST-80).
- You can register your own custom C-functions in a private main.c and relink ST/X from the binaries.
- (see the demo functions provided in main.c).
- Notice, that custom functions are ugly and inflexible.
- They are to be considered obsolete and support for them will vanish.

If you have the stc compiler, we recommend using either inline primitive
code or the new external function call interface which is based upon libffi.
