I just had a quick look at kern_sendfile() in uipc_syscalls.c. It seems that it
uses virtual memory for the file access, so this won't work on RTEMS. However
it would be nice to have an optimized sendfile() which avoids one copy and uses
mbufs directly.

Okay, So I will dig in to the details of the implementation of sendfile on
freebsd to find if it does indeed use mmap, or if there is an
implementation that doesn't.
I will inform as soon as I figure it out if this is the correct way out.
Thanks and Regards,

I agree with Sebastian.
Using read write in a loop can only serve as a makeshift measure.
If we have consensus here, then I can work on getting sendfile backed up in
libbsd. (though, I have some serious background reading to do before I am
able to do it, but I think I can. )
Thanks and Regards,
I would use the sendfile system call implementation from FreeBSD and add it to
the libbsd. Its not a big win if you use read() and write() to implement
sendfile(). This makes only sense if you can use kernel space zero-copy
buffers.

Sujay,
Monkey use conditionals for each implementation: Linux, FreeBSD and OSX. My
suggestion is that RTEMS may implement a sendfile based on FreeBSD format
which can easily be emulated as a read() and further write() for socket
operations. That will help not only Monkey, but also other software t

Sendfile is not specified in POSIX.1-2001 or other standards and its
implementations vary depending on the unix/linux system being used.
Freebsd has sendfile in its libc.
FreeBSD has a completely d
