Subject: Re: MSVC8 CRT "Secure Template Overloads" feature and stdcxx
Since va_list can be anything, we need to pass va_list type in
function call.
We can add function template <class T> get_t () { T t;
return t; } to
the libc_decl.sh and use the followinf declaration:
vsprintf((char*)0,0,get_t<va_list>())
in headers.inc.
Wouldn't vsprintf((char*)0,0,va_list()) work?
I think this should work.
My concern here is with the va_list name: Is it required to be
declared in the same header as the functions that use it?
On gcc 3.4.4/Cygwin the va_list type is not defined in stdio.h.
Right. The C standard requires that <stdarg.h> be #included
before calling vsnprintf(). To do what you want you'd need
to find a way (ideally a general mechanism) to also #include
<stdarg.h> in these tests.
So what's the status of this improvement? I didn't mean to shoot
it down completely, just point out the problem with it on other
platforms. Since this is an MSVC-specific feature it wouldn't be
completely inappropriate to devise an MSVC-specific solution for
it.
