英文:
Why windows wifi API 'WlanEnumInterfaces' is failed with 'ERROR_INVALID_STATE'?
问题
以下是代码的中文翻译部分：
我正在尝试使用Windows API枚举WiFi网络，但我不知道为什么会出现错误代码ERROR_INVALID_STATE。以下是我的示例代码：
PWLAN_INTERFACE_INFO_LIST pIfList = NULL;
DWORD dwNegotiatedVersion;
HANDLE hClientHandle;
DWORD Res = WFDOpenHandle(WFD_API_VERSION, &dwNegotiatedVersion, &hClientHandle);
if (Res != ERROR_SUCCESS)
{
WFDCloseHandle(hClientHandle);
return;
}
Res = WlanEnumInterfaces(hClientHandle, NULL, &pIfList);
if (Res == ERROR_INVALID_STATE)
{
WlanCloseHandle(hClientHandle, NULL);
return;
}
else if (Res != ERROR_SUCCESS)
{
WlanCloseHandle(hClientHandle, NULL);
return;
}
我正在使用Windows 10，并使用Visual Studio 2015进行调试。

WlanEnumInterfaces 中的句柄是从 WlanOpenHandle 获得的句柄，如文档所述。它不是来自 WFDOpenHandle 的 WFD 句柄。
英文:
The handle for WlanEnumInterfaces is a handle from WlanOpenHandle - as stated in the documentation. It is not a WFD handle from WFDOpenHandle.
