Re: C++: operator new and disabled exceptions

["Richard Li" <richardpku at gmail dot com>]

Hi,

I tried to redefine the global "new" operator like the following code,
and it seems to work.

#include <new>
void * operator new (size_t n)
{
 return operator new (n, std::nothrow);
}

void * operator new [] (size_t n)
{
 return operator new [] (n, std::nothrow);
}
