 * iperlsys.h - Perl's interface to the system

/*
 *      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
 *
