Expand description

@brief Erase all key-value pairs in a namespace

Note that actual storage may not be updated until nvs_commit function is called.

@param[in] handle Storage handle obtained with nvs_open. Handles that were opened read only cannot be used.

@return - ESP_OK if erase operation was successful - ESP_FAIL if there is an internal error; most likely due to corrupted NVS partition (only if NVS assertion checks are disabled) - ESP_ERR_NVS_INVALID_HANDLE if handle has been closed or is NULL - ESP_ERR_NVS_READ_ONLY if handle was opened as read only - other error codes from the underlying storage driver
