Comment on memcopy, memmove, and Speed over Safety by David

I disagree, is usually obvious when using memcpy that memory will never overlap, and thus no danger. The function is commonly used by others (so not making code harder to follow for sake of efficiency.

If you are going to add inefficiency, then do it where mistakes actually commonly happen. (Eg buffer overruns, including strings, and pointers to memory that has not been allocated or already been freed, including from bad error handling.)

Speed: there are many different ways to do both memcpy and memmove in real world, so one situation doesn’t mean much. Intel processors for example have dedicated memcpy type instructions, and sometimes SSE instruction set. Most modern processors can move 4 bytes much faster than 1.

BS.

[[window standardWindowButton:NSWindowZoomButton] setEnabled:NO];
[window setStyleMask:window.styleMask^NSResizableWindowMask];

This is how you do it since Mac OS X 10.0.

+1 for immediate autorelease. In fact, if you’re using the empty constructor, then I’m pretty sure you can use `new` instead of `alloc, init, autorelease`.

Foo* pityTheFoo = [Foo new];

Hi,
Just to tell you that I love your blog, so much useful information about Obj-C, finally a good source of detailed examples that can (and will) for sure improve my Obj-C coding habits.
I’m used to develop C for electronic as profession but now I’m trying learn Obj-C for some personal projects.

Thanks for everything!

Best Regards,
