Hi all,
Can I read data from a socket (non blocking datagram socket) at
a specific offset? like we do lseek() on a file descriptor?

also, can I use the MSG_PEEK flag to traverse the socket
queue repeatedly?

Thanks in advance for your help.

man lseek says:
ERRORS
..
ESPIPE
The fildes argument is associated with a pipe, a FIFO,
or a socket.

No.

No, and you should definitely *not* want to. Your program's primary
obligation is to keep the queue empty.
