A question regarding try/catch

[GCDEF]

More typically you'd throw in the function and put the try/catch in the function that calls it. That way you'd know if it returned legitimately or threw the exception.

void bar()
{
    try
    {
          if(foo())
                ...
    }
    catch(...)
    {
        ...
    }
}

If you need the catch in foo, typically returning true would indicate foo succeeded, and false would indicated it didn't.
