This page describes my proposal for development of new standard low-level I/O library Bulatz 09:29, 13 March 2007 (UTC)

The existing GHC I/O library (based on using Handles) is very feature-rich, but it cannot be extended any more. The reason is that this library has non-modular design where all features are closely coupled with each other and GHC RTS. But we need to further extend it, adding the follwoing facilities:

  • More models for async i/o (support for kqueue,epoll,AIO)
  • Unicode filenames on windows and unix
  • Using ByteString/UTF8String/UTF16String for filenames
  • Files>4gb on windows
  • Memory-mapped files
  • ByteString i/o
  • Binary i/o and binary serialization
