hello list
a very simple question i hope
how do we access the guile posix/sockets functions from within an r6rs
library?
in ikarus there is (import (ikarus)), is it something similar?
i see they are automatically present in the interpreter
best,
rohan
$ guile --r6rs
GNU Guile 3.0.4
[...]
scheme@(guile-user)> socket
$1 = #<procedure socket (_ _ _)>
scheme@(guile-user)>
$ cat test.scm
#!r6rs
(library (test)
(export udp-open)
(import (rnrs))
(define udp-open
(lambda (h p)
(let ((s (socket PF_INET SOCK_DGRAM 0)))
(connect s AF_INET (inet-pton AF_INET h) p)
(list s h p)))))
$ guile --r6rs
GNU Guile 3.0.4
[...]
scheme@(guile-user)> (import (test))

(import (guile)) does the trick.
