Comment(by bonefish):

 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.
