Assuming that means the usual "error codes are positive" issue, then
B_USE_POSITIVE_POSIX_ERRORS and libposix_error_mapper.a can simplify things
tremendously. Care must be taken in the Haiku-native part (where it
interfaces with POSIX API or the portable code), for which the helper macros
in
<Errors.h> can be of assistance. Other than that things should simply work.
