// This file defines a macro:
|
|
// ASSERT_TASK_NOT_PREEMPTED()
|
|
// This macro is used to declare that the current scope is not expected to yield.
|
|
// If the task does yield, it will generate an assertion.
|
|
//
|
|
// Use this when you you're coding somethign that must not yield, and you think you
|
|
// have done it (just by virtue of the fact that you don't think you've called any
|
|
// functions that could yield). This will help detect when your assumptions are
|
|
// wrong and you accidentally call something that yields.
|
|
//
|
|
// This has no cost in release mode, and is extremely cheap in debug mode.
