Well, it's a c++ feature for easier "error-handling" or "exception-handling".

Yes, you are correct, it's c++.

Here's the source I compiled:

#include <iostream.h>
	
void f(int x) throw(int)
{
	if (x > 10)
		throw(x);

	cout << "f: " << x << endl;
}
	
int main(void)
{
	try
	{
		f(5);
		f(9);
		f(11);
	}
	catch(int i)
	{
        	cout << "Error: Argument to f() was too large (" << i << ")" << endl;
	}
	return 0;
}


When compiled with the PGCC release based on EGCS 1.0.1 the output is the
following:

f: 5
f: 9
Abort!

i.e. when the exception are thrown as 11 is passed to f(), I just get the
abort message. When compiled with GCC 2.8.0 (under linux) the output is the
following:

f: 5
f: 9
Error: Argument to f() was too large (11)

i.e. the expected output (atleast what I expected).

Greatful for any replies.
