/*
* 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).
*

/*
* 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
*
