6.14.10 R6RS I/O Ports

The I/O port API of the Revised Report^6 on the Algorithmic Language Scheme (R6RS) is provided by the (rnrs io ports) module. It provides features, such as binary I/O and Unicode string I/O, that complement or refine Guile’s historical port API presented above (see section Input and Output).

Note: The implementation of this R6RS API is not complete yet.

A subset of the (rnrs io ports) module is provided by the (ice-9 binary-ports) module. It contains binary input/output procedures and does not rely on R6RS support.
