#ifndef _PERLIO_H
#define _PERLIO_H
/*
  Interface for perl to IO functions.
  There is a hierachy 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_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 compatability mode for some specialist applications.

                 If USE_SFIO is not set then 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.
