The G++ 1.32 (SunOs 3.5, Sun 3/60)
complains about this program:
===========================
#define NULL 0
typedef void (*exceptionTrapTy)(unsigned&, int& ...);
class ExceptionTrap {
exceptionTrapTy old_trap;
public:
ExceptionTrap(exceptionTrapTy xtrap =NULL);
~ExceptionTrap();
};
void xtrap(unsigned& err, int& sev)
{
err= 0;
sev= 0;
}
main()
{
ExceptionTrap x(xtrap); // Error ?!, fix by using:
// ExceptionTrap x(&xtrap);
}
========================
