wlanapi.h) (WLAN_QOS_INFO 结构

重要

某些信息与预发行产品相关，该产品在商业发布之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。

表示有关 WFA 的 Wi-Fi QoS 管理规范中概述并在 802.11 规范中定义的四项功能的信息。

语法

typedef struct _WLAN_QOS_INFO {
  WLAN_QOS_CAPABILITIES    interfaceCapabilities;
  BOOL                     bConnected;
  WLAN_CONNECTION_QOS_INFO connectionQoSInfo;
} WLAN_QOS_INFO, *PWLAN_QOS_INFO;

成员

interfaceCapabilities

类型： WLAN_QOS_CAPABILITIES

接口的 QoS 功能。

bConnected

类型： BOOL

表示是否已建立连接。 如果 TRUE为 ，则 connectionQoSInfo 保存有关当前连接的 QoS 信息。 否则， connectionoQoSInfo 将被归零。

connectionQoSInfo

类型： WLAN_CONNECTION_QOS_INFO

有关与当前连接相关的 WFA Wi-Fi QoS 管理规范) 概述的 QoS (功能的信息。 仅当 bConnected 为 TRUE时，此结构才包含相关信息;否则全为零，应忽略它。
