I'm wondering why this macro does not appear anywhere in this repository, despite being a significant feature (direct vs. deferred post) described in the uCOS-III book?

Thanks!

The feature was dropped many years ago. I believe the reason was that the overhead was too large for an ISR, and the code itself added needless complexity.

Thanks for the clarification @forg0ne. So you mean the "deferred" post feature was dropped and all posts are "direct"?

That's correct.
