//========================================================================
 
// CONFIGURATION
 
#include <pkgconf/libc_stdio.h>   // Configuration header
 
// INCLUDES
 
#include <cyg/infra/cyg_type.h> // common type definitions and support
#include <stdarg.h>             // va_list from compiler
 
// CONSTANTS
 
// Some of these values are odd to ensure that asserts have better effect
// should spurious values be passed to functions expecting these constants.
 
// _IOFBF, _IOLBF, and _IONBF specify full, line or no buffering when used
// with setvbuf() - ISO C standard chap 7.9.1
 
#define _IOFBF      (-2)
#define _IOLBF      (-4)
#define _IONBF      (-8)
 
// EOF is a macro defined to any negative integer constant - ISO C standard
// chap. 7.9.1
#define EOF         (-1)
 
// SEEK_CUR, SEEK_END and SEEK_SET are used with fseek() as position
// anchors - ISO C standard chap. 7.9.1
#define SEEK_SET    0
#define SEEK_CUR    1
#define SEEK_END    2
 
 
// TYPE DEFINITIONS
 
// A type capable of specifying uniquely every file position - ISO C
// standard chap 7.9.1
typedef cyg_ucount32 fpos_t;
 
 
// FILE is just cast to an address here. It is uncast internally to the
// C library in stream.hxx  as the C++ Cyg_StdioStream class.
// Optional run-time checking can be enabled to ensure that the cast is
// valid, using the standard assertion functionality.
//
// The array size is irrelevant other than being more than 8, and is present
// to stop references to FILEs being marked as able to be put in the small
// data section. We can't just mark it as in the ".data" section as on some
// targets it may actually be ".common".
typedef CYG_ADDRESS FILE[9999];
 
// EXTERNAL VARIABLES
 
// Default file streams for input/output. These only need to be
// expressions, not l-values - ISO C standard chap. 7.9.1
//
// CYGPRI_LIBC_STDIO_NO_DEFAULT_STREAMS is used when initializing
// stdin/out/err privately inside the C library
