Function otPlatSettingsSet

pub unsafe extern "C" fn otPlatSettingsSet(
    aInstance: *mut otInstance,
    aKey: u16,
    aValue: *const u8,
    aValueLength: u16,
) -> otError

Sets or replaces the value of a setting.

Sets or replaces the value of a setting identified by @p aKey.

Calling this function successfully may cause unrelated settings with multiple values to be reordered.

OpenThread stack guarantees to use otPlatSettingsSet() method for a @p aKey that was either previously set using otPlatSettingsSet() (i.e., contains a single value) or is empty and/or fully deleted (contains no value).

Platform layer can rely and use this fact for optimizing its implementation.

@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 @p 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 changed or staged. @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.
