Subject: [Bug c++/28308] New: Language linkage not part of function type
Date: Fri, 07 Jul 2006 19:28:00 -0000 [thread overview]
Message-ID: <bug-28308-11686@http.gcc.gnu.org/bugzilla/> (raw)
>From the C++ standard, 7.5p1:
Two function types with different language linkages are distinct types even if
they are otherwise identical.
The following code tests for this and should compile (a successful compile
indicates a test pass).
template <bool>
struct static_assert;
template<>
struct static_assert<true> {};
extern "C"
{
char myexit(void (*)(void));
typedef void (*CF)(void);
}
int myexit(void (*f)())
{
static_assert<sizeof(myexit((CF)f)) == 1> e1;
return myexit((CF)f);
}
int main()
{
}
extern "C"
{
char myexit(void (*)(void))
{
return 0;
}
}
