/**
|

* @file px4_macros.h |
||||
* |
||||
* A set of useful macros for enhanced runtime and compile time |
||||
* error detection and warning suppression. |
||||
* |
||||
* Define NO_BLOAT to reduce bloat from file name inclusion. |
||||
* |
||||
* The arraySize() will compute the size of an array regardless |
||||
* it's type |
||||
* |
||||
* INVALID_CASE(c) should be used is case statements to ferret out |
||||
* unintended behavior |
||||
* |
||||
* UNUSED(var) will suppress compile time warnings of unused |
||||
* variables |
||||
* |
||||
* CCASSERT(predicate) Will generate a compile time error it the |
||||
* predicate is false |
