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