關于無線承載網絡
無線承載網絡(Wireless Hosted Network)是指安裝有無線局域網服務的Windows 7和Windows Server 2008 R2所提供的一種WLAN功能，具備兩項主要功能：
第一、把一個物理無線網卡虛擬化成一個或多個虛擬無線網卡，稱為虛擬的WiFi。
第二、借助無線網卡把當前接網絡虛擬成為一個基于軟件的無線接入點，稱為虛擬AP或軟AP。
=========================萬惡的分割線===========================
項目需要包含wlanapi.h 頭文件和wlanapi.lib 庫
備注：測試環境win7_64,建議關閉一些安全軟件，（比如我測試的時候忘了關comodo導致防火墻總是拒絕其他設備的連接）。
=============================================================
功能不復雜，用到的主要函數有下面幾個
1.調用WlanOpenHandled得到一個連接hClientHandle，下面的操作都要用到這個連接。當然程序退出的時候記得調用WlanCloseHandle關閉這個連接。
DWORD WINAPI WlanOpenHandle( _In_ DWORD dwClientVersion, _Reserved_ PVOID pReserved, _Out_ PDWORD pdwNegotiatedVersion, _Out_ PHANDLE phClientHandle ); DWORD WINAPI WlanCloseHandle( _In_ HANDLE hClientHandle, _Reserved_ PVOID pReserved );
2.下面的函數用來設置承載網絡的一些屬性。
DWORD WINAPI WlanHostedNetworkSetProperty(
_In_ HANDLE hClientHandle,
_In_ WLAN_HOSTED_NETWORK_OPCODE OpCode,
_In_ DWORD dwDataSize,
_In_ PVOID pvData,
_Out_opt_ PWLAN_HOSTED_NETWORK_REASON pFailReason,
_Reserved_ PVOID pvReserved
);typedef enum _WLAN_HOSTED_NETWORK_OPCODE {
wlan_hosted_network_opcode_connection_settings, //設置一些連接屬性
wlan_hosted_network_opcode_security_settings, //設置安全屬性
wlan_hosted_network_opcode_station_profile, //query the wireless Hosted Network station profile
wlan_hosted_network_opcode_enable //query or set the wireless Hosted Network enabled flag
} WLAN_HOSTED_NETWORK_OPCODE, *PWLAN_HOSTED_NETWORK_OPCODE;3.啟用和禁用無線承載網絡。
打開網絡和共享中心 單擊更改適配器設置，如果啟用了無線承載網絡 面板里面就會有描述為Microsoft Virtual WiFi Miniport Adapter的一個虛擬網卡。禁用之后這個虛擬網卡就會消失了。
當然只有啟用了無線承載網絡才能分享wifi啦
DWORD WINAPI WlanHostedNetworkForceStart( _In_ HANDLE hClientHandle, _Out_opt_ PWLAN_HOSTED_NETWORK_REASON pFailReason, _Reserved_ PVOID pvReserved );
DWORD WINAPI WlanHostedNetworkForceStop( _In_ HANDLE hClientHandle, _Out_opt_ PWLAN_HOSTED_NETWORK_REASON pFailReason, _Reserved_ PVOID pvReserved );
4.連接和斷開網絡
DWORD WINAPI WlanHostedNetworkStartUsing( _In_ HANDLE hClientHandle, _Out_opt_ PWLAN_HOSTED_NETWORK_REASON pFailReason, _Reserved_ PVOID pvReserved );
DWORD WINAPI WlanHostedNetworkStopUsing( _In_ HANDLE hClientHandle, _Out_opt_ PWLAN_HOSTED_NETWORK_REASON pFailReason, _Reserved_ PVOID pvReserved );
5.用來查詢承載網絡的網絡狀況。
DWORD WINAPI WlanHostedNetworkQueryStatus( _In_ HANDLE hClientHandle, _Out_ PWLAN_HOSTED_NETWORK_STATUS *ppWlanHostedNetworkStatus, _Reserved_ PVOID pvReserved );
typedef struct _WLAN_HOSTED_NETWORK_STATUS {
WLAN_HOSTED_NETWORK_STATE HostedNetworkState;
GUID IPDeviceID;
DOT11_MAC_ADDRESS wlanHostedNetworkBSSID;
DOT11_PHY_TYPE dot11PhyType;
ULONG ulChannelFrequency;
DWORD dwNumberOfPeers; //已連接的節點數目
WLAN_HOSTED_NETWORK_PEER_STATE PeerList[1]; //存放節點信息的數組
} WLAN_HOSTED_NETWORK_STATUS, *PWLAN_HOSTED_NETWORK_STATUS;
typedef struct _WLAN_HOSTED_NETWORK_PEER_STATE {
DOT11_MAC_ADDRESS PeerMacAddress; //節點設備的MAC地址
WLAN_HOSTED_NETWORK_PEER_AUTH_STATE PeerAuthState; //節點的認證狀態
} WLAN_HOSTED_NETWORK_PEER_STATE, *PWLAN_HOSTED_NETWORK_PEER_STATE;調用WlanHostedNetworkQueryStatus將得到一個WLAN_HOSTED_NETWORK_STATUS結構體，就可以查詢一些網絡基本信息了，比如dwNumberOfPeers連接到這個網絡的節點數，PeerList數組存放著對應節點的詳細信息，包括MAC地址和認證狀態。
6.用來設置密碼
注意密碼長度必須 大于8 小于63 否則會調用失敗
DWORD WINAPI WlanHostedNetworkSetSecondaryKey( _In_ HANDLE hClientHandle, _In_ DWORD dwKeyLength, _In_ PUCHAR pucKeyData, _In_ BOOL bIsPassPhrase, _In_ BOOL bPersistent, _Out_opt_ PWLAN_HOSTED_NETWORK_REASON pFailReason, _Reserved_ PVOID pvReserved );
