Some low level utilities

More often to build other abstractions than used directly.


  • A restricted channel to pass data from signal handler.
  • Module with the self-pipe pattern.


  • A bare libc abort.
  • Emulates the behaviour of a default handler for the provided signal.
  • A bare libc exit.
  • The usual raise, just the safe wrapper around it.
  • Registers an arbitrary action for the given signal.
  • Provides a human-readable name of a signal.
  • Removes a previously installed action.
