Can you kindly show me where BBitmap throws if it fails to allocate? I
can't find it.
"new" *always* throws. That's what new(std::nothrow) prevents.
Only in the latter case you must check for NULL.
Since throwing exceptions is not common throughout the Be API
(unfortunately), you need to make sure that even if bad_alloc is thrown,
all objects are cleaned up as they would have when you return B_NO_MEMORY.
From APIs, it is expected to return an error code rather than throwing
an exception. As a general rule, if you return a status_t, don't throw.
Within applications, you can use exceptions however you want to, though.
