Subject: GNU C++ Exception handling
PostBoxID v02.0-061-000350133
Hello help-gcc,

I would like to find out how to use the exception handling mechanism supported by GNU C++.

We use GCC 2.4.5 configured for i386-unknown-sco3.2v4.0 (and at home on i386-unknown-linux).

The GDB Info page reads under the node <Exception Handling> "Some languages, such as GNU C++,
implement exception handling". The Info page for GCC however, makes no reference to this
feature. Looking at the source for GCC, I found the file cp-except.c which implements the
exception handling mechanism. Armed with the ARM I tried to implement the following test:

#include <iostream.h>

void f()
{
    throw("Help");
}

main()
{
    try
    {
        f();
    }
    catch (const char* p)
    {
         cerr << "catch : " << p << endl;
    }
}

When I compiled this with "c++ -g -c except.cc", it said that "throw" and "try" were undeclared
and "catch" was thought to be a function.

Can I use the GNU C++ exception handing in our configuration, and if so, could you please provide
me with a simple example on how to use it?

Many Thanks,
