Using strings for binary I/O is Bad because it assumes a specific bit-representation of strings (namely, ASCII). SRFI-4 vectors and `uniform-vector-read!'/`uniform-vector-write' may be a better match. If you're not afraid of using experimental code, you might also want to try Guile-R6RS-Libs, which includes part of R6RS' binary I/O API (actually based on R5.92RS): http://www.laas.fr/~lcourtes/software/guile/guile-r6rs-libs-0.0.tar.gz http://www.r6rs.org/document/lib-html-5.92/r6rs-lib-Z-H-4.html#node_chap_2 http://www.r6rs.org/document/lib-html-5.92/r6rs-lib-Z-H-9.html#node_sec_7.2 Thanks, Ludovic. _______________________________________________ Guile-user mailing list Guile-user@gnu.org http://lists.gnu.org/mailman/listinfo/guile-user
