Improved attempt:

DESCRIPTION
This call copies data between one file descriptor and another. The
descriptor from which data is read cannot be a socket but must
correspond to a file which supports mmap()-like operations. in_fd
should be a filedescriptor opened for reading and out_fd should be a
descriptor opened for writing. Because this copying is done within
the kernel, sendfile() does not need to spend time transfering data
to and from userspace.
