	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).

	17	* PerlXXX_YYY explained - DickH and DougL @ ActiveState.com
	18	*
	19	* XXX := functional group
	20	* YYY := stdlib/OS function name
	21	*
	22	* Continuing with the theme of PerlIO, all OS functionality was
	23	* encapsulated into one of several interfaces.
	24	*
	25	* PerlIO - stdio
	26	* PerlLIO - low level I/O
	27	* PerlMem - malloc, realloc, free
	28	* PerlDir - directory related
	29	* PerlEnv - process environment handling
	30	* PerlProc - process control
	31	* PerlSock - socket functions
	32	*
	33	*
	34	* The features of this are:
	35	* 1. All OS dependant code is in the Perl Host and not the Perl Core.
	36	* (At least this is the holy grail goal of this work)
	37	* 2. The Perl Host (see perl.h for description) can provide a new and
	38	* improved interface to OS functionality if required.
	39	* 3. Developers can easily hook into the OS calls for instrumentation
	40	* or diagnostic purposes.
	41	*
	42	* What was changed to do this:
	43	* 1. All calls to OS functions were replaced with PerlXXX_YYY
	44	*
