Which functions are you referring to? Usually you send UDP packets using
socket interface (using read/write or sendto/recvfrom). These are all
in place (and BTW these are system calls and not library functions).
Of course, other socket-related system calls are there, like
socket(), bind(), etc.

Hostname resolution is currently a little worse than you might expect
a standard linux system, (e.g. hosts file is not searched, "search"
directive in resolv.conf doesn't seem to work, etc.) but is still

BTW, NFS (which uses RPC over UDP) is working fine and is quite stable
(at least from UDP-related point of view) on uClinux.

Happy hacking,
