// Purpose:       Initialization of stdin stream for ISO C library
// Description:   We put all this in a separate file in the hope that if
//                no-one uses stdin, then it is not included in the image
// Usage:

// CONFIGURATION

#include <pkgconf/libc_stdio.h>          // Configuration header

// Don't let us get the stream definitions of stdin/out/err from stdio.h
// since we are going to break the type safety :-(
#define CYGPRI_LIBC_STDIO_NO_DEFAULT_STREAMS

// And we don't need the stdio inlines, which will otherwise complain if
// stdin/out/err are not available
#ifdef CYGIMP_LIBC_STDIO_INLINES
# undef CYGIMP_LIBC_STDIO_INLINES
#endif

// INCLUDES

#include <cyg/infra/cyg_type.h>           // Common type definitions and support
#include <cyg/libc/stdio/stream.hxx>      // Cyg_StdioStream class
#include <cyg/libc/stdio/stdiofiles.hxx>  // C library files
#include <cyg/libc/stdio/stdiosupp.hxx>   // Cyg_libc_stdio_find_filename()

// CONSTANTS

// Use default libc priority to allow it to be the fd 0 if necessary
#define PRIO (CYG_INIT_LIBC)

// STATICS
