Adds a value to a setting ** This function adds the value to a setting
- identified by aKey, without replacing any existing
- values.
- Note that the underlying implementation is not required
- to maintain the order of the items associated with a
- specific key. The added value may be added to the end,
- the beginning, or even somewhere in the middle. The order
- of any pre-existing values may also change.
- Calling this function successfully may cause unrelated
- settings with multiple values to be reordered.
- @param[in] aInstance The OpenThread instance structure.
- @param[in] aKey The key associated with the setting to change.
- @param[in] aValue A pointer to where the new value of the setting should be read from. MUST NOT be NULL
-
if aValueLength is non-zero.
- @param[in] aValueLength The length of the data pointed to by aValue. May be zero.
- @retval OT_ERROR_NONE The given setting was added or staged to be added.
- @retval OT_ERROR_NOT_IMPLEMENTED This function is not implemented on this platform.
- @retval OT_ERROR_NO_BUFS No space remaining to store the given setting. */
