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 that can be
7  * #defined to the system-level function (or a wrapper provided elsewhere).

16  *      PerlXXX_YYY explained - DickH and DougL @ ActiveState.com
17  *
18  * XXX := functional group
19  * YYY := stdlib/OS function name
20  *
21  * Continuing with the theme of PerlIO, all OS functionality was encapsulated
22  * into one of several interfaces.
23  *
24  * PerlIO - stdio
25  * PerlLIO - low level I/O
26  * PerlMem - malloc, realloc, free
27  * PerlDir - directory related
28  * PerlEnv - process environment handling
29  * PerlProc - process control
30  * PerlSock - socket functions
31  *
32  *
33  * The features of this are:
34  * 1. All OS dependant code is in the Perl Host and not the Perl Core.
35  *    (At least this is the holy grail goal of this work)
36  * 2. The Perl Host (see perl.h for description) can provide a new and
37  *    improved interface to OS functionality if required.
38  * 3. Developers can easily hook into the OS calls for instrumentation
39  *    or diagnostic purposes.
40  *
41  * What was changed to do this:
42  * 1. All calls to OS functions were replaced with PerlXXX_YYY
43  *
