simple-sendfile-0.2.27: Cross platform library for the sendfile system call

System.Linux.Sendfile

Synopsis

# Documentation

sendfile :: Fd -> ByteString -> FileRange -> IO () -> IO () Source #

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 bofore waiting the socket to be ready for writing.
