Implement conditional replacement for printf() family functions.
|
||||
|
||||
* include/_mingw.h (__USE_MINGW_ANSI_STDIO): New macro; define it.
|
||||
(__MINGW_ANSI_STDIO__): New manifest constant; define as bitmapped
|
||||
flag for use in user specified __MINGW_FEATURES__ attribute.
|
||||
(__MINGW_LC_MESSAGES__, __MINGW_LC_ENVVARS__): New manifest constants;
|
||||
currently unused: reserved as components of...
|
||||
(__MINGW_LC_EXTENSIONS__): ...this new manifest constant; earmarked as
|
||||
a __MINGW_FEATURES__ enhancement to setlocale().
|
||||
|
||||
* include/stdio.h (__mingw_printf, __mingw_vprintf): Prototype them.
|
||||
(__mingw_fprintf, __mingw_vfprintf): Likewise.
|
||||
(__mingw_sprintf, __mingw_vsprintf): Likewise.
|
||||
(__msvcrt_printf, __msvcrt_vprintf): Likewise.
|
||||
(__msvcrt_fprintf, __msvcrt_vfprintf): Likewise.
|
||||
(__msvcrt_sprintf, __msvcrt_vsprintf): Likewise.
|
||||
(printf, vprintf) [!__USE_MINGW_ANSI_STDIO]: Prototype for default
|
||||
usage; link to DLL import stub, importing from MSVCRT.
|
||||
(fprintf, vfprintf) [!__USE_MINGW_ANSI_STDIO]: Likewise.
|
||||
(sprintf, vsprintf) [!__USE_MINGW_ANSI_STDIO]: Likewise.
|
||||
(printf) [__USE_MINGW_ANSI_STDIO]: Redirect to __mingw_printf; use
|
||||
locally defined static stub implementation.
|
||||
(fprintf, sprintf) [__USE_MINGW_ANSI_STDIO]: Likewise; redirect to
|
||||
__mingw_fprintf and __mingw_sprintf respectively.
|
||||
(vprintf) [__USE_MINGW_ANSI_STDIO]: Redirect to __mingw_vprintf; use
|
||||
static inline implementation for C++ and GNU C, or locally defined
|
||||
static stub otherwise.
|
||||
(vfprintf, vsprintf) [__USE_MINGW_ANSI_STDIO]: Likewise; redirect to
|
||||
__mingw_vfprintf and __mingw_vsprintf respectively.
