Subject: [PATCH 1/1] linux ttyname{_r}: return ENODEV not ENOENT
While musl correctly detects whether the pts device a given file descriptor
refers to can be retrieved it returns ENOENT. We've recently upstreamed a patch
to glibc which uses ENODEV. This has been after a discussion about what would be
most in line with POSIX. Additionally we fixed a bunch of programs to handle the
ENODEV case. It would be good if musl would also set ENODEV instead of ENOENT to
enable programs to have uniform handle on this case.
