Foreign Library Interface
نویسنده
چکیده
We present an improved Foreign Function Interface (FFI) for R to call arbitary native functions without the need for C wrapper code. Further we discuss a dynamic linkage framework for binding standard C libraries to R across platforms using a universal type information format. The package rdyncall comprises the framework and an initial repository of crossplatform bindings for standard libraries such as (legacy and modern) OpenGL, the family of SDL libraries and Expat. The package enables systemlevel programming using the R language; sample applications are given in the article. We outline the underlying automation tool-chain that extracts cross-platform bindings from C headers, making the repository extendable and open for library developers.

The Layers of Larceny’s Foreign Function Interface
The Foreign Function Interface (FFI) in Larceny supports interacting with dynamically loaded C libraries via glue code written in Scheme. The programmer does not need to develop any C code to interface with C libraries. The FFI is divided into layers of Larceny Scheme code; the lower layers implement kernel functionality, and the higher layers support portable glue code development. The lower l...

We present PLTplot, a plotting package for PLT Scheme. PLTplot provides a basic interface for producing common types of plots such as line and vector field plots from Scheme functions and data, an advanced interface for producing customized plot types, and support for standard curve fitting. It incorporates renderer constructors, transformers from data to its graphical representation, as values...
متن کاملA Foreign-Function Interface Generator for occam-pi
occam-pi is a programming language based on the CSP process algebra and the pi-calculus, and has a powerful syntax for expressing concurrency. occam-pi does not however, come with interfaces to a broad range of standard libraries (such as those used for graphics or mathematics). Programmers wishing to use these must write their own wrappers using occam-pi’s foreign function interface, which can...
متن کاملA Framework for Using Aldor Libraries with Maple
This paper examines what is required to use Aldor libraries to extend Maple in an effective and natural way. This represents a non-traditional approach to structuring computer algebra software: using an efficient, compiled language, designed for writing large complex mathematical libraries together with a top-level system based on userinterface priorities and ease of scripting. Our method invol...
متن کاملInvestigating the Level of Observing the Evaluation Criteria for User Interface in library services providing to the blind and deaf users in the word
Purpose: Digital library user interfaces has a determining role in desirable performance of this kind of libraries. Digital Library service providers to the blind and deaf users will have their best performance when the users (deaf and blind users) could have a proper interaction with them. This study aims to evaluate and analyze the criteria related to user interface in digital libraries servi...
