Network.Sendfile
Description
Cross platform library for the sendfile system call. This library tries to call minimum system calls which are the bottleneck of web servers.
- sendfile :: Socket -> FilePath -> FileRange -> IO () -> IO ()
- sendfileWithHeader :: Socket -> FilePath -> FileRange -> IO () -> [ByteString] -> IO ()
- sendfileFd :: Socket -> Fd -> FileRange -> IO () -> IO ()
- sendfileFdWithHeader :: Socket -> Fd -> FileRange -> IO () -> [ByteString] -> IO ()
- data FileRange
- = EntireFile
- | PartOfFile { }

sendfile :: Socket -> FilePath -> FileRange -> IO () -> IO ()
Simple binding for sendfile() of BSD and MacOS.
- Used system calls: open(), sendfile(), and close().
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 bofore waiting the socket to be ready for writing.
sendfileWithHeader :: Socket -> FilePath -> FileRange -> IO () -> [ByteString] -> IO ()
Simple binding for sendfile() of BSD and MacOS.
- Used system calls: open(), sendfile(), and close().
The fifth header is also sent with sendfile(). If the file is small enough, the header and the file is send in a single TCP packet on FreeBSD. MacOS sends the header and the file separately but it is fast.
