__throw ???

I can't find any information on this anywhere! Does anyone know how I can use this cool add-on?

Code:

---

#include <stdio.h>
#include <al/etl.h>
#include <sfl.h>


void hello( void ) __THROW
{
        puts( "Hello" );
}

int main( void )
{
        hello( );

        return EXIT_SUCCESS;
}

well there are three ways to get somewhere with this faster than waiting for the off chance somebody knows how to use this... Read your compiler doc's, search google, or learn C++.

Have you thought about looking at your compiler's documentation? Instead of you know posting everything you see something you don't understand?

Of course I did.

info gcc
/_THROW
/__throw

Didn't find anything. Unless of course you know a better place for compiler documentation? I also tried Google frequently and could not find any solid information about __THROW or _THROW.
