There are two implementations of this SRFI, Scsh version 0.7,
which can be found at GitHub in the scsh repository of scheme,
and a Chibi Scheme (srfi 170) library. You can find the Chibi Scheme example implementation,
and build notes for scsh, in their own srfi subdirectories.
This file documents the current exceptions and deviations of the Chibi Scheme implementation.
Note generally that the Chibi implementation is completely thread-naive.
The implementation gets and sets errno
at the Scheme level, and arbitrary code that might
change errno can run between the time a system or
library call sets its value due to an error and Scheme code gets
the current value.
The open-file and fd->port procedures
do not support either the buffer-mode argument or
the binary-input/output value of the port-type argument.
The implementation of call-with-temporary-filename is
neither finished or exported.
