Oh man, yes you are right read2_cb is getting called but with pending as UV_UNKNOWN_HANDLE. So we cant wrap arbitrary file descriptor/handle ??
The code will look too clumsy if I try to mix libuv and "credential passing" using sendmsg and recvmsg outside of libuv. Or may be I can add libuv call to pass arbitray handle itself after understanding the libuv code. What do you suggest ?
