-- Simple binding for sendfile() of Linux.
-- Used system calls:
--
-- - EntireFile -- open(), stat(), sendfile(), and close()
--
-- - PartOfFile -- open(), sendfile(), and close()
--
-- If the size of the file is unknown when sending the entire file,
-- specifying PartOfFile is much faster.
--
-- The fourth action argument is called when a file is sent as chunks.
-- Chucking is inevitable if the socket is non-blocking (this is the
-- default) and the file is large. The action is called after a chunk
-- is sent and before waiting the socket to be ready for writing.
