Hi,
I know about sendfile api which can be used to implement zero copy for sending data over socket. But I want to implement zero copy on socket receiving side. I looked at the kernel code and found that mmap is also not available on socket.
Is it possible to implement zerocopy on socket receive without modifying kernel code?
or is there any api/syscall available for it?
thanks for any help,
