That would be great, thanks :)
I'm honestly surprised that those buffers are so small, even in glibc.
Sure, it takes up static space, and in practice a small value works for
most people since it will usually be /dev/something, but since ttyname()
is not supposed to ever fail with ERANGE or any kind of overflow, I was
expecting the buffer to be PATH_MAX bytes. Or even dynamically (re)allocated -
which would pull in malloc(), but text space + a bit of heap space is cheaper
than static space.
