lfn serial ticket/834-toolchain-update topic/msim-upgrade topic/simplify-dev-export
Last change on this file since bd01a4e was 2721a75, checked in by Martin Decky <martin@…>, 15 years ago

ping overhaul:

  • coding style
  • shorter and better readable main()
  • tool output is much similar to GNU's ping, demonstrating what functionality is still missing

related changes:

  • rename strerror.h → str_error.h for consistency
  • replace network apps' specific command-line parsing functions with a generalized libc versions
  • Property mode set to 100644
