I am interesting in handling errors
when using the sockets layer functions of LWIP.
I have already read the pdf documentation
where it is said that the BSD socket library provides no such error handling
due to the fact that it is a simple reference implementation. But I have
also seen in the code that there is an error table already defined:
Can these error codes be directly used
with the provided BSD sockets layer? Or I should look for another implementation
which returned these error codes? I have had a look in the code and I understand
that in the provided socket implementation only a few error codes are returned.
Actually, I vas making a comparison
with the win32 socket implementation, and I would like to achieve a function
similar to that WSAGetLastError in win32 for those who are familiar to
the platform.
I have also seen that in the socket
structure below (lwip_socket), there are sometimes used some of these codes
(in err), and I think that this structure might should be read to make
a proper error handling.
I would thank any recommendation from
you dealing with the problem.
