2 * iperlsys.h - Perl's interface to the system
3 *
4 * This file defines the system level functionality that perl needs.
5 *
6 * When using C, this definition is in the form of a set of macros
7 * that can be #defined to the system-level function (or a wrapper
8 * provided elsewhere).
9 *
10 * When using C++ with -DPERL_OBJECT, this definition is in the
11 * form of a set of virtual base classes which must be subclassed to
12 * provide a real implementation. The Perl Object will use instances
13 * of this implementation to use the system-level functionality.

22 * PerlXXX_YYY explained - DickH and DougL @ ActiveState.com
23 *
24 * XXX := functional group
25 * YYY := stdlib/OS function name
26 *
27 * Continuing with the theme of PerlIO, all OS functionality was
28 * encapsulated into one of several interfaces.
29 *
30 * PerlIO - stdio
31 * PerlLIO - low level I/O
32 * PerlMem - malloc, realloc, free
33 * PerlDir - directory related
34 * PerlEnv - process environment handling
35 * PerlProc - process control
36 * PerlSock - socket functions
37 *
38 *
39 * The features of this are:
40 * 1. All OS dependant code is in the Perl Host and not the Perl Core.
41 * (At least this is the holy grail goal of this work)
42 * 2. The Perl Host (see perl.h for description) can provide a new and
43 * improved interface to OS functionality if required.
44 * 3. Developers can easily hook into the OS calls for instrumentation
45 * or diagnostic purposes.
46 *
47 * What was changed to do this:
48 * 1. All calls to OS functions were replaced with PerlXXX_YYY
49 *
