* libguile/r6rs-ports.c (scm_get_string_n_x): Implement `get-string-n!' in C for efficiency. * libguile/r6rs-ports.h: Add prototype for this function. * module/ice-9/binary-ports.scm: Export `get-string-n!'. * module/rnrs/io/ports.scm (get-string-n): Implement based on `get-string-n!'. Export both `get-string-n!' and `get-string-n'. * module/rnrs.scm: Also export these. * test-suite/tests/r6rs-ports.test (8.2.9 Textual input): Add a few tests for `get-string-n' and `get-string-n!'.

|
;;; The I/O port API of the R6RS is provided by this module. In many areas
|
|
;;; it complements or refines Guile's own historical port API. For instance,
|
|
;;; it allows for binary I/O with bytevectors.
