Foreign function interface, or FFI, is a common name for a facility in a programming language (especially a high-level one that does not usually work in terms of pointers, raw structure layout, etc.) to invoke functions and access data structures defined using another one (especially C).
The term is commonly used in Common Lisp and Haskell.
Relevant tasks
Functions
- Call foreign language function
- Call function in shared library (a special case)
- Use another language to call a function
Data structures/memory access
- Address Operations
- Data Representation
- Host Introspection
