Hackage :: [Package]

clock: High-resolution clock and timer functions: realtime, monotonic, cputime, etc.

[ bsd3, library, system ] [ Propose Tags ]

A package for convenient access to high-resolution clock and timer functions of different operating systems.

It is planned to consist of two layers. The lower layer will provide direct access to OS-specific clock and timer functions like clock_gettime of Posix or GetTickCount of Windows and its upper layer shall then provide a common API for all supported systems. Currently only the lower level is being developed.

POSIX reference: IEEE Std 1003.1-2008 http://www.opengroup.org/onlinepubs/9699919799/, http://www.opengroup.org/onlinepubs/9699919799/functions/clock_getres.html#

WINDOWS reference: !! This early version is posix-only and does not build on Windows. Support will be added in the future. !!

DESCRIPTION

  see
  http://sert.homedns.org/hs/clock/dist/doc/html/clock/


  0.1.2 (current version)

  System
    Posix
      Clock


  1.0.0 (future projection)

  System
    Clock
    Posix
      Clock
    Windows
      Clock


----------------

CONSIDERATIONS

  → Implement System.Windows.Clock using QueryPerformanceCounter,
    GetTickCount64, etc. and export a common interface in another
    module System.Clock

  → System.Posix.Clock:
    getRes has type 'Clock → IO TimeSpec' discuss changing this to
    'Clock → TimeSpec' with other haskell developers or read the
    IEEE Std 1003.1-2008 thoroughly and decide on what to do.

  → System.Posix.Clock:
    move to a more flexible clock_id representation so that we can
    get the process/thread cpu-time for not just the caller but any
    process/thread for which we can obtain a correspoinding clock_id

  → Namespaces:
    use *.Clocks instead of *.Clock?


----------------

KNOWN ISSUES

  → namespace(s) have not been confirmed final.

  → posix-only: windows implementation to be added later.

  → no tests.
