The purpose of this project is to gain a better understanding of Foreign Function Interfaces. Foreign function interfaces are a way for a program in one language to execute code written in another language.
The goal of this project is to explore the FFI to C in a number of languages. This will ideally achieve multiple goals: to serve as an example repository for future personal usage, as well as (hopefully) provide some simple tests in each language to test the performance of the interface.
There is a small toy library in C called set-c. This library implements
a generic set in C using void pointers. This library will be used in each language to do a small set of operations.
The usage of foreign functions in each language should follow typical conventions/coding style of that language.
For example, C++ is an OOP language and set-c is not OOP, but easily fits the OOP model. Therefore, a wrapper
class is written in C++.
After a few languages are supported, a standard set of tests will be developed to evalute the performance of the FFI in each language.
There is a directory for each language. For ease of building the code, a makefile is provided in each one.
Run make in the directory to build the binary.
