## Elements

`apiid` | ID of the API that acts as the source for the callback generation. This argument is the same as the `WMApiid` enumerated type. Here, it is fixed as `WM_APIID_START_CONNECT`.
`errcode` | Result of the asynchronous process. It is equivalent to the `WMErrCode` enumerated type.
`wlCmdID` | If errcode is `WM_ERRCODE_FAILED`, this function will store the ID of the command that was in error in the wireless firmware.
`wlResult` | If errcode is `WM_ERRCODE_FAILED`, this function will store the code was the source of the error in the wireless firmware.
`state` | If `errcode` is `WM_ERRCODE_SUCCESS`, the WM Cause Code generated by the callback is stored. There are five possible causes:. `WM_STATECODE_CONNECT_START、WM_STATECODE_CONNECTED、WM_STATECODE_BEACON_LOST、WM_STATECODE_DISCONNECTED、WM_STATECODE_DISCONNECTED_FROM_MYSELF。`
`aid` | If `state` is `WM_STATECODE_CONNECTED`, the AID that is allocated by the parent will be stored.
`reason` | Code showing the reason for disconnection when the state is `WM_STATECODE_DISCONNECTED` or `WM_STATECODE_DISCONNECTED_FROM_MYSELF`. This member is used internally in the library for debugging.
`wlStatus` | If the errcode is `WM_ERRCODE_FAILED`, the code that represents the status of the connection partner that caused the connection failure. This member is used internally in the library for debugging.
`macAddress` | If `state` is `WM_STATECODE_CONNECTED` or `WM_STATECODE_DISCONNECTED_FROM_MYSELF`, the MAC address of the parent will be stored.

## Description

This structure is passed to the callback function related to `WM_StartConnect`.
