Well, they'd have to be using specific exception handlers to get the
error message. Perhaps they just have one per wrapper function like
this (assuming their exception objects ultimately inherit from
std::exception, which they all ought to):
...
char* error_string;
...
catch(const std::exception& e)
{
error_string = malloc(strlen(e.what()) + 1 );
if(error_string != NULL)
strcpy(error_string, e.what());
return false;
}
// They could add this catch-all, which we could fall back on to be on
the safe side
catch(...)
{
// We can't do anything except swallow - this could be anything
that doesn't inherit from std::exception
}
