Replying to [comment:2 kaliber]:
> You are right. I thought the POSIX codes are positive.
They are indeed. For compatibility with BeOS Haiku has to use negative
error codes, though. If a piece of software you're using requires positive
error codes, there's an experimental (possibly not yet complete) way to do
that:
- Define the macro B_USE_POSITIVE_POSIX_ERRORS when compiling the code.
- Link everything against libposix_error_mapper.a.
- When mixing code using POSIX and Haiku API, the macros
B_{FROM,TO}_POSIX_ERROR() have to be used explicitly.
> But the test case does not work properly in Haiku. The function should
return EINVAL instead of ETIMEDOUT. If you want, I can create a new
ticket.
Please do. I don't want to work on this stuff ATM. Maybe someone else
does.
