WLAN_QOS_INFO結構 (wlanapi.h)

重要

有些資訊與發行前版本產品有關，在正式發行前可能會大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。

代表 WFA Wi-Fi QoS 管理規格中所述之四項功能的相關信息，並定義於 802.11 規格中。

語法

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

成員

interfaceCapabilities

類型： WLAN_QOS_CAPABILITIES

介面的 QoS 功能。

bConnected

類型： BOOL

表示是否有已建立的連接。 如果 TRUE為 ， 則 connectionQoSInfo 會保存目前連線的 QoS 資訊。 否則， connectionoQoSInfo 將會為零。

connectionQoSInfo

類型： WLAN_CONNECTION_QOS_INFO

WFA Wi-Fi QoS 管理規格) 與目前連線相關的 QoS 功能相關信息 (。 只有當 bConnected 為 TRUE時，此結構才會包含相關信息;否則為零，您應該忽略它。
