关于无线承载网络
无线承载网络(Wireless Hosted Network)是指安装有无线局域网服务的Windows 7和Windows Server 2008 R2所提供的一种WLAN功能，具备两项主要功能：
第一、把一个物理无线网卡虚拟化成一个或多个虚拟无线网卡，称为虚拟的WiFi。
第二、借助无线网卡把当前接网络虚拟成为一个基于软件的无线接入点，称为虚拟AP或软AP。
=========================万恶的分割线===========================
项目需要包含wlanapi.h 头文件和wlanapi.lib 库
备注：测试环境win7_64,建议关闭一些安全软件，（比如我测试的时候忘了关comodo导致防火墙总是拒绝其他设备的连接）。
=============================================================
功能不复杂，用到的主要函数有下面几个
1.调用WlanOpenHandled得到一个连接hClientHandle，下面的操作都要用到这个连接。当然程序退出的时候记得调用WlanCloseHandle关闭这个连接。
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.下面的函数用来设置承载网络的一些属性。
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, //设置一些连接属性
wlan_hosted_network_opcode_security_settings, //设置安全属性
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.启用和禁用无线承载网络。
打开网络和共享中心 单击更改适配器设置，如果启用了无线承载网络 面板里面就会有描述为Microsoft Virtual WiFi Miniport Adapter的一个虚拟网卡。禁用之后这个虚拟网卡就会消失了。
当然只有启用了无线承载网络才能分享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.连接和断开网络
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.用来查询承载网络的网络状况。
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; //已连接的节点数目
WLAN_HOSTED_NETWORK_PEER_STATE PeerList[1]; //存放节点信息的数组
} WLAN_HOSTED_NETWORK_STATUS, *PWLAN_HOSTED_NETWORK_STATUS;
typedef struct _WLAN_HOSTED_NETWORK_PEER_STATE {
DOT11_MAC_ADDRESS PeerMacAddress; //节点设备的MAC地址
WLAN_HOSTED_NETWORK_PEER_AUTH_STATE PeerAuthState; //节点的认证状态
} WLAN_HOSTED_NETWORK_PEER_STATE, *PWLAN_HOSTED_NETWORK_PEER_STATE;调用WlanHostedNetworkQueryStatus将得到一个WLAN_HOSTED_NETWORK_STATUS结构体，就可以查询一些网络基本信息了，比如dwNumberOfPeers连接到这个网络的节点数，PeerList数组存放着对应节点的详细信息，包括MAC地址和认证状态。
6.用来设置密码
注意密码长度必须 大于8 小于63 否则会调用失败
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 );
