HKMGetKeyboardLEDState 获得键盘LED灯状态

功能

获得键盘Num Lock、Caps Lock、Scroll Lock灯的状态

参数

• 参数1: 设备对象：无类型指针。使用HKMOpen可以创建它。
• 参数2: 键盘灯：无符号32位整型数，可取值如下：
  • 0: Num Lock灯
  • 1: Caps Lock灯
  • 2: Scroll Lock灯

返回值

布尔值。灯亮返回True，灯灭返回False

C#例子

uint dwDevId;
IntPtr lpDev;
bool numLockState;
dwDevId = SkmCore.HKMSearchDevice(0x1234, 0xABCD, 0);
if (dwDevId == 0xFFFFFFFF)
{
    Console.WriteLine("未找到键鼠模拟器");
    return;
}
lpDev = SkmCore.HKMOpen(dwDevId, 0);
if (lpDev == IntPtr.Zero)
{
    Console.WriteLine("打开键鼠模拟器失败");
    return;
}
numLockState = SkmCore.HKMGetKeyboardLEDState(lpDev, 0);
Console.WriteLine($"NumLock：{(numLockState ? "亮" : "灭")}");
SkmCore.HKMClose(lpDev);

C语言例子

DWORD dwDevId;
LPVOID lpDev;
dwDevId=HKMSearchDevice(0x1234,0xABCD,0);
if(dwDevId==0xFFFFFFFF)
{
    printf("未找到键鼠模拟器\n");
    return 0;
}
lpDev=HKMOpen(dwDevId,0);
if(lpDev==NULL)
{
    printf("打开键鼠模拟器失败\n");
    return 0;
}
printf("NumLock：%s\n",HKMGetKeyboardLEDState(lpDev,0)?"亮":"灭");
HKMClose(lpDev);
