/*
Interface for perl to IO functions.
There is a hierarchy of Configure determined #define controls:
- USE_STDIO - forces PerlIO_xxx() to be #define-d onto stdio functions.
- This is used for x2p subdirectory and for conservative
- builds - "just like perl5.00X used to be".
- This dominates over the others.
+ USE_STDIO - No longer available via Configure. Formerly forced
+ PerlIO_xxx() to be #define-d onto stdio functions.
+ Now generates compile-time error.
USE_PERLIO - The primary Configure variable that enables PerlIO.
- If USE_PERLIO is _NOT_ set
- then USE_STDIO above will be set to be conservative.
- If USE_PERLIO is set
- then there are two modes determined by USE_SFIO:
-
- USE_SFIO - If set causes PerlIO_xxx() to be #define-d onto sfio functions.
- A backward compatibility mode for some specialist applications.
-
- If USE_SFIO is not set then PerlIO_xxx() are real functions
+ PerlIO_xxx() are real functions
defined in perlio.c which implement extra functionality
required for utf8 support.
- One further note - the table-of-functions scheme controlled
- by PERL_IMPLICIT_SYS turns on USE_PERLIO so that iperlsys.h can
- #define PerlIO_xxx() to go via the function table, without having
- to #undef them from (say) stdio forms.
