What is midipix, and how is it different? + +midipix is a development environment that lets you create programs +for Windows using the standard C and POSIX APIs. No compromises made, +no shortcuts taken. + +If you are interested in cross-platform programming that reclaims +the notion of write once, compile everywhere; if you believe that the +'standard' in the C Standard Library should not be a null signifier; +and if you like cooking your code without #ifdef hell and low-level +minutiae, then this page is for you. + +midipix makes cross-platform programming better, simpler and faster, +specifically by bringing a modern, conforming C Runtime Library to the +Windows platform. While the idea itself is not new, the approach taken +in midipix to code portability is radically different from that found +in other projects. + +*(reproduced from [[2](https://midipix.org/#sec-midipix)])* + +[Back to top](#table-of-contents) + +[//]: "}}}" + +[//]: # "{{{ 2.
