/* vfprintf.c
|

|
|
*
|

|
|
* $Id$
|
||
|
|
*
|
||
|
|
* Provides an implementation of the "vfprintf" 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 "vfprintf" will normally be invoked by calling
|
||
|
|
* "__mingw_vfprintf()" in preference to a direct reference to "vfprintf()"
|
||
|
|
* itself; this leaves the MSVCRT implementation as the default, which
|
||
|
|
* will be deployed when user code invokes "vfprint()". Users who then
|
||
|
|
* wish to use this implementation may either call "__mingw_vfprintf()"
|
||
|
|
* directly, or may use conditional preprocessor defines, to redirect
|
||
|
|
* references to "vfprintf()" to "__mingw_vfprintf()".
|
||
|
|
*
|
||
|
|
* Compiling this module with "-D INSTALL_AS_DEFAULT" will change this
|
||
|
|
* recommended convention, such that references to "vfprintf()" in user
|
||
|
|
* code will ALWAYS be redirected to "__mingw_vfprintf()"; if this option
|
||
|
|
* is adopted, then users wishing to use the MSVCRT implementation of
|
||
|
|
* "vfprintf()" 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_vfprintf()"; however,
|
||
|
|
* since users may not expect this behaviour, a standard libmingwex.a
|
||
|
|
* installation does not employ this option.
