Description
Cross platform library for the sendfile system call. This library tries to call minimum system calls which are the bottleneck of web servers.
Documentation
sendfile :: Socket -> FilePath -> 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.
File range for sendfile.
