Cannot open file "/dev/urandom" OS Explanation: (errno == 0) Success
Hi Jean-Claude, it is not possible to open /dev/urandom: (with-open-file (s "/dev/urandom" :element-type '(unsigned-byte 8)) (read-byte s)) Filesystem error with pathname: "/dev/urandom". Cannot open file OS Explanation: (errno == 0) Success [Condition of type SI:OS-FILE-ERROR] but this works: (with-open-file (s "/etc/passwd" :element-type '(unsigned-byte 8)) (read-byte s)) Thank you, Tomas

This fix is now in github repo master head. #'cl:probe-file was too selective in its file type tastes... Thank you for pointing it. JCB
