   In software design, the Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by [1] native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.

7. Foreign function interface - Wikipedia

   en.wikipedia.org/wiki/Foreign_function_interface

   A foreign function interface (FFI) is a mechanism by which a program written in one programming language can call routines or make use of services written or compiled in another one. An FFI is often used in contexts where calls are made into a binary dynamic-link library .
