/*
 * iperlsys.h - Perl's interface to the system
 *
 * This file defines the system level functionality that perl needs.
 *
 * When using C, this definition is in the form of a set of macros
 * that can be #defined to the system-level function (or a wrapper
 * provided elsewhere).
 *
 * When using C++ with -DPERL_OBJECT, this definition is in the
 * form of a set of virtual base classes which must be subclassed to
 * provide a real implementation.  The Perl Object will use instances
 * of this implementation to use the system-level functionality.

/*
 *	PerlXXX_YYY explained - DickH and DougL @ ActiveState.com
 *
 * XXX := functional group
 * YYY := stdlib/OS function name
 *
 * Continuing with the theme of PerlIO, all OS functionality was
 * encapsulated into one of several interfaces.
 *
 * PerlIO - stdio
 * PerlLIO - low level I/O
 * PerlMem - malloc, realloc, free
 * PerlDir - directory related
 * PerlEnv - process environment handling
 * PerlProc - process control
 * PerlSock - socket functions
 *
 *
 * The features of this are:
 * 1. All OS dependant code is in the Perl Host and not the Perl Core.
 *    (At least this is the holy grail goal of this work)
 * 2. The Perl Host (see perl.h for description) can provide a new and
 *    improved interface to OS functionality if required.
 * 3. Developers can easily hook into the OS calls for instrumentation
 *    or diagnostic purposes.
 *
 * What was changed to do this:
 * 1. All calls to OS functions were replaced with PerlXXX_YYY
 *
