description="
Foreign function call libraries.

GNU libffcall is a collection of four libraries which can be used to
build foreign function call interfaces in embedded interpreters:

* avcall
Calling C functions with variable arguments.

* vacall
C functions accepting variable argument prototypes.

* trampoline
Closures as first-class C functions.

* callback
Closures with variable arguments as first-class C functions
(a reentrant combination of vacall and trampoline).
