Hello,
I am trying to implement my own transport layer protocol in Linux for
an experiment. I am going to use socket interface and add my protocol
using sock_register. For the proto_ops i can see that the parameters
for the sendmsg and recvmsg are (struct kiocb *iocb, struct socket
*sock, struct msghdr *msg, size_t len, int flags). But there are three
types of user api's send, sendto, sendmsg. Of these three only sendmsg
contains a parameter for msghdr. I find that the other two api's are
incompatible with the parameters supplied by the kernel to my kernel-
space sendmsg function. So what happens when we use send and sendto
user-space api's? Hope i am clear..

Thanks,
Bala
