请问下：
CC3200 SDK 1.3.0 中，example/wlan_station 中,
typedef enum{
// Choosing -0x7D0 to avoid overlap w/ host-driver's error codes
LAN_CONNECTION_FAILED = -0x7D0,
INTERNET_CONNECTION_FAILED = LAN_CONNECTION_FAILED - 1,
DEVICE_NOT_IN_STATION_MODE = INTERNET_CONNECTION_FAILED - 1,
STATUS_CODE_MAX = -0xBB8
}e_AppStatusCodes;
而/example/http_clent_demo中，
// Application specific status/error codes
typedef enum{
/* Choosing this number to avoid overlap with host-driver's error codes */
DEVICE_NOT_IN_STATION_MODE = -0x7D0,
DEVICE_START_FAILED = DEVICE_NOT_IN_STATION_MODE - 1,
INVALID_HEX_STRING = DEVICE_START_FAILED - 1,
TCP_RECV_ERROR = INVALID_HEX_STRING - 1,
TCP_SEND_ERROR = TCP_RECV_ERROR - 1,
FILE_NOT_FOUND_ERROR = TCP_SEND_ERROR - 1,
INVALID_SERVER_RESPONSE = FILE_NOT_FOUND_ERROR - 1,
FORMAT_NOT_SUPPORTED = INVALID_SERVER_RESPONSE - 1,
FILE_OPEN_FAILED = FORMAT_NOT_SUPPORTED - 1,
FILE_WRITE_ERROR = FILE_OPEN_FAILED - 1,
INVALID_FILE = FILE_WRITE_ERROR - 1,
SERVER_CONNECTION_FAILED = INVALID_FILE - 1,
GET_HOST_IP_FAILED = SERVER_CONNECTION_FAILED - 1,
STATUS_CODE_MAX = -0xBB8
}e_AppStatusCodes;
却是这样定义的，请问，怎样定义返回值，两个工程不一样。在哪里定义
