|
|
*
|
|
* @warning IMPORTANT: When comparing NV_STATUS_LEVEL(_S) against one of
|
|
* these constants, it is important to use '<=' or '>' (rather
|
|
* than '<' or '>=').
|
|
*
|
|
* For example. do:
|
|
* if (NV_STATUS_LEVEL(status) <= NV_STATUS_LEVEL_WARN)
|
|
* rather than:
|
|
* if (NV_STATUS_LEVEL(status) < NV_STATUS_LEVEL_ERR)
|
|
*
|
|
* By being consistent in this manner, it is easier to systematically
|
|
* add additional level constants. New levels are likely to lower
|
|
* (rather than raise) the severity of _ERR codes. For example,
|
|
* if we were to add NV_STATUS_LEVEL_RETRY to indicate hardware
|
|
* failures that may be recoverable (e.g. RM_ERR_TIMEOUT_RETRY
|
|
* or RM_ERR_BUSY_RETRY), it would be less severe than
|
|
* NV_STATUS_LEVEL_ERR the level to which these status codes now
|
|
* belong. Using '<=' and '>' ensures your code is not broken in
|
|
* cases like this.
