Package frysk.sys Description

This package exports interfaces to the underlying native linux system.

Overview

The frysk.sys package provides the client with direct access to a number of underlying linux kernel and libc interfaces.

Note that, where possible, the interfaces have attempted to be event-driven friendly. For instance, Wait notifies the client of wait status information by calling the applicable frysk.sys.Wait#Observer method and not by returning a status object.

Errors

Should an underlying system call return an error indication then that error is propagated up the call chain by throwing a Errno run-time exception.
