Compiler-specific Features
Usage
If the compiler knows that a function can never throw out, it might be able to generate
smaller exception-handling tables for callers of that function.
Restrictions
If a call to a function results in a C++ exception being propagated from the call into the
caller, the behavior is undefined.
This modifier is ignored when not compiling with exceptions enabled.
Example
struct S
{
~S();
};
__declspec(nothrow) extern void f(void);
void g(void)
{
S s;
f();
}

4.2.6 __declspec(notshared)
The __declspec(notshared) attribute prevents a specific class from having its virtual
functions table and RTTI exported. This holds true regardless of other options you
apply. For example, the use of --export_all_vtbl does not override
__declspec(notshared).
Example
struct __declspec(notshared) X
{
virtual int f();
}; // do not export this
int X::f()
{
return 1;
}
