The net_getsockname() function seems to be missing. I added the following implementation and it seems to work:


s32 net_getsockname(s32 s, struct sockaddr *addr, socklen_t *addrlen)
{
STACK_ALIGN(u32, _socket, 1, 32);
STACK_ALIGN(u8, _addr, sizeof(struct sockaddr), 32);
s32 ret;

if (net_ip ...

In network.h, there's only struct sockaddr and struct sockaddr_in, but no struct sockaddr_storage. struct sockaddr_storage is defined by POSIX. It should be a struct big enough to hold any sockaddr_* struct in the system. The following simple definition will suffice:


struct sockaddr_storage {
u8 ...

When trying to net_bind() to port 0, the bind fails instead of choosing a free port. I can't find anything in POSIX about this (it says it's protocol-dependent), but every OS seems to handle it that way.

When trying to use net_gethostbyname() with an IP, it returns a resolve error.

This not only means that you have to check whether the address is an IP first and then use inet_addr(), it also means it breaks with how gethostbyname() works on any other OS, thus making ports unnecessarily hard ...
