關(guān)于無線承載網(wǎng)絡(luò)
無線承載網(wǎng)絡(luò)(Wireless Hosted Network)是指安裝有無線局域網(wǎng)服務(wù)的Windows 7和Windows Server 2008 R2所提供的一種WLAN功能，具備兩項(xiàng)主要功能：
第一、把一個(gè)物理無線網(wǎng)卡虛擬化成一個(gè)或多個(gè)虛擬無線網(wǎng)卡，稱為虛擬的WiFi。
第二、借助無線網(wǎng)卡把當(dāng)前接網(wǎng)絡(luò)虛擬成為一個(gè)基于軟件的無線接入點(diǎn)，稱為虛擬AP或軟AP。
=========================萬惡的分割線===========================
項(xiàng)目需要包含wlanapi.h 頭文件和wlanapi.lib 庫
備注：測試環(huán)境win7_64,建議關(guān)閉一些安全軟件，（比如我測試的時(shí)候忘了關(guān)comodo導(dǎo)致防火墻總是拒絕其他設(shè)備的連接）。
=============================================================
功能不復(fù)雜，用到的主要函數(shù)有下面幾個(gè)
1.調(diào)用WlanOpenHandled得到一個(gè)連接hClientHandle，下面的操作都要用到這個(gè)連接。當(dāng)然程序退出的時(shí)候記得調(diào)用WlanCloseHandle關(guān)閉這個(gè)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(shù)用來設(shè)置承載網(wǎng)絡(luò)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(shè)置一些連接屬性
wlan_hosted_network_opcode_security_settings, //設(shè)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(wǎng)絡(luò)。
打開網(wǎng)絡(luò)和共享中心 單擊更改適配器設(shè)置，如果啟用了無線承載網(wǎng)絡(luò) 面板里面就會(huì)有描述為Microsoft Virtual WiFi Miniport Adapter的一個(gè)虛擬網(wǎng)卡。禁用之后這個(gè)虛擬網(wǎng)卡就會(huì)消失了。
當(dāng)然只有啟用了無線承載網(wǎng)絡(luò)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(wǎng)絡(luò)
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(wǎng)絡(luò)的網(wǎng)絡(luò)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(jié)點(diǎn)數(shù)目
WLAN_HOSTED_NETWORK_PEER_STATE PeerList[1]; //存放節(jié)點(diǎn)信息的數(shù)組
} WLAN_HOSTED_NETWORK_STATUS, *PWLAN_HOSTED_NETWORK_STATUS;
typedef struct _WLAN_HOSTED_NETWORK_PEER_STATE {
DOT11_MAC_ADDRESS PeerMacAddress; //節(jié)點(diǎn)設(shè)備的MAC地址
WLAN_HOSTED_NETWORK_PEER_AUTH_STATE PeerAuthState; //節(jié)點(diǎn)的認(rèn)證狀態(tài)
} WLAN_HOSTED_NETWORK_PEER_STATE, *PWLAN_HOSTED_NETWORK_PEER_STATE;調(diào)用WlanHostedNetworkQueryStatus將得到一個(gè)WLAN_HOSTED_NETWORK_STATUS結(jié)構(gòu)體，就可以查詢一些網(wǎng)絡(luò)基本信息了，比如dwNumberOfPeers連接到這個(gè)網(wǎng)絡(luò)的節(jié)點(diǎn)數(shù)，PeerList數(shù)組存放著對(duì)應(yīng)節(jié)點(diǎn)的詳細(xì)信息，包括MAC地址和認(rèn)證狀態(tài)。
6.用來設(shè)置密碼
注意密碼長度必須 大于8 小于63 否則會(huì)調(diào)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 );
