They are in a single range across the project, look at _FX_ and _KNOWNHOST_
errors. For example:
LIBSSH2_KNOWNHOST_CHECK_MISMATCH 1
LIBSSH2_FX_EOF 1
These types of collisions are not great, IMHO.
They are the same values because they actually are in different ranges. But I
also recognize that it isn't very ovious since the functions all just return
'int' - which I think is unfortunate but really a design choice made back in
the days we still lived in caves.
Changing them to different typedef'ed variables depending on what error code
range they return would be a good thing for a future API update.
we have a function like errorMessageFromCode(int code), the _code_ is the
code coming from any o’l libssh function call.
But that's the mistake. All libssh2 functions don't return the same error code
set. The libssh2_knownhost*() functions for example only return error codes in
the LIBSSH2_KNOWNHOST_CHECK_* series.
