data from one file descriptor to another.

note that this function is highly platform dependent.

| sendfile |
| :: Fd | Input | | -> Fd | Output | | -> Int | Offset | | -> Int | Nr. of bytes to transmit | | -> IO () | | | sendfile transmits the contents of an open file to a stream socket
opened for writing with as little overhead as possible.
This function is not defined by any standard! Passing '0' will indeed
transmit nothing at all.
Caveats for converting a Handle to Fd apply. |

|
| sendfileByName :: String -> Fd -> IO () |
| sendfileByName sends a file to an already open descriptor
using sendfile. You can only use this function on regular
files. |
