The FreeBSD C99 & POSIX Conformance Project aims to implement all requirements of the ISO 9899:1999 (C99) and IEEE 1003.1-2001 (POSIX) standards. In cases where aspects of these standards cannot be followed, those aspects will be documented in the c99(7) or posix(7) manuals. It is also an aim of this project to implement regression tests to ensure correctness whenever possible.
All of the initial development will take place in the 5.0-CURRENT branch and hopefully most of the changes will eventually be merged into the 4-STABLE branch. Since this is a rather large project and is being done on a volunteer basis, there is no set schedule.
The project is always looking for additional contributors. If you wish to participate, the best way to find out what is happening is to subscribe to the freebsd-standards mailing list. If you are working on a specific task relating to the project, you should contact mike@FreeBSD.org with a description of the task so that your task can be listed below.
ISO/IEC 9899:1999, also known as C99, is available for purchase in electronic form from the American National Standards Institute, or available from the International Organization for Standardization store in electronic and paper form.
IEEE Std 1003.1-2001 - The free (registration required), online version of POSIX.1-2001 and SUSv3 standard.
Are you Ready For C99? - This article discusses some of the new features in C99.
Most discussion relating to this project takes place on the &a.standards; mailing list. To subscribe to the list, send a message to &a.majordomo; with "subscribe freebsd-standards" in the body of the text.
Jens Schweikhardt maintains a list with the current status of POSIX Utility Conformance in FreeBSD.
