Detailed Description
Simple atomic uint32_t API (get, set, increment, decrement).
Implements atomic values which can be safely updated across threads.
This API allows you to maintain a uint32_t value across threads safely. The operations are to get, set, increment and decrement. For the increment and decrement operations return the new value.
