- ipdir.h
- Interface for perl directory functions

-/*
- 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
