We would rather use the ucrt for these, but sometimes dependencies on the mingw stdio functions creep in. 仕方ない. The cost is only paid if they are used; otherwise the symbols are garbage-collected at link time.

|
*
|
|
* Provides an implementation of the "printf" function, conforming
|
|
* generally to C99 and SUSv3/POSIX specifications, with extensions
|
|
* to support Microsoft's non-standard format specifications. This
|
|
* is included in libmingwex.a, whence it may replace the Microsoft
|
|
* function of the same name.
|
|
*
|
|
* Written by Keith Marshall <keithmarshall@users.sourceforge.net>
|
|
*
|
|
* This implementation of "printf" will normally be invoked by calling
|
|
* "__mingw_printf()" in preference to a direct reference to "printf()"
|
|
* itself; this leaves the MSVCRT implementation as the default, which
|
|
* will be deployed when user code invokes "print()". Users who then
|
|
* wish to use this implementation may either call "__mingw_printf()"
|
|
* directly, or may use conditional preprocessor defines, to redirect
|
|
* references to "printf()" to "__mingw_printf()".
|
|
*
|
|
* Compiling this module with "-D INSTALL_AS_DEFAULT" will change this
|
|
* recommended convention, such that references to "printf()" in user
|
|
* code will ALWAYS be redirected to "__mingw_printf()"; if this option
|
|
* is adopted, then users wishing to use the MSVCRT implementation of
|
|
* "printf()" will be forced to use a "back-door" mechanism to do so.
|
|
* Such a "back-door" mechanism is provided with MinGW, allowing the
|
|
* MSVCRT implementation to be called as "__msvcrt_printf()"; however,
|
|
* since users may not expect this behaviour, a standard libmingwex.a
|
|
* installation does not employ this option.
