Eiffel POSIX binding

e-POSIX gives Eiffel programmers access to the familiar Unix API. Either as raw calls, but also in the form of classes with full Design By Contract support. e-POSIX file and socket classes can be used as a plugin where Gobo's KI_INPUT_STREAM and KI_OUTPUT_STREAM are expected. So you can now directly parse input coming from a TCP socket.

The goal of e-POSIX is to provide a 100% complete Eiffel binding to Standard C, POSIX and the Single Unix Specification.

e-POSIX can also be used on Windows systems through its portability layer. This allows you to create native Windows programs that use file descriptors, sockets, pipes and can read and write the input and output of child programs. The Cygwin UNIX emulator is also supported, but not needed. When using Cygwin, e-POSIX just thinks that it is running on Unix.

e-POSIX got a 2nd place at the Eiffel struggle 2000!

Released on 2010 January 13 is version 3.2.0, the current official release. It is targeted at ISE 6.4 (and 6.5), the Gobo Eiffel compiler, and SmartEiffel 1.2r7. The most important user visible list of changes between 3.0 and 3.2 is:

Licence changes to MIT.
Support for the Gobo Eiffel compiler.
MD5, SHA1 and HMAC calculation.
EPX_FILE_SYSTEM: newly created directories are now also accessible by everyone unless modified by umask.
ABSTRACT_INTERNET_SOCKET/ABSTRACT_TCP_SOCKET: features set_no_delay and set_throughput to optimise specific TCP transmission patterns.
STDC_BUFFER: 64 bit integer read/write routines.
Logging framework switched to NET_LOGGER.
Signal and exit handling rewritten, no longer uses cecil.
VisualEiffel support dropped.
