[-- Attachment #1 --] Hi, I am implementing a small BSD socket layer which supports only the AF_INET family. I am wondering whether recvmsg() and sendmsg() calls are required for the INET protocol family. I don't know if I should implemented it or not. I have looked up some open source projects and grepped for recvmsg and sendmsg calls but couldn't find any. How often do people use recvmsg/sendmsg() calls (also readv()/writev()) in their BSD socket based Internet applications? Is it safe NOT to implement these functions for a INET socket? Thanks.
