According to the manual:
6.12.2 Binary I/O
-----------------
[...]
To use these routines, first include the binary I/O module:
(use-modules (ice-9 binary-ports))
[...]
The end-of-file object is unlike any other kind of object: it’s not a
pair, a symbol, or anything else. To check if a value is the
end-of-file object, use the ‘eof-object?’ predicate.
-- Scheme Procedure: eof-object? x
-- C Function: scm_eof_object_p (x)
Return ‘#t’ if X is an end-of-file object, or ‘#f’ otherwise.
However, eof-object? is not exported by (ice-9 binary-ports):
scheme@(guile-user)> (@ (ice-9 binary-ports) eof-object?)
ice-9/boot-9.scm:1685:16: In procedure raise-exception:
Unbound variable: eof-object?
But it is imported from (ice-9 ports):
scheme@(guile-user) [1]> (@ (ice-9 ports) eof-object?)
$1 = #<procedure eof-object? (_)>
Could an appropriate export be added to (ice-9 binary-ports)?
Or the manual adjusted to note you need to import (ice-9 ports)
to get eof-object?
Greetings,
Maxime

Isn't eof-object? available in the default environment?

Yes, but I use (define-library ...) and (library ...) forms
instead of (define-module (...) ...) forms. When using
define-library or library, the ‘default’ environment is ignored.
I suppose I should import 'eof-object?' from (rnrs io ports)
as I am using RnRS library forms. Still, this seems a bug in
(ice-9 binary-ports) or the documentation and easy to fix.
Greetings,
Maxime.
