如何使用IOKit写入IOHIDDevice端点

#import <IOKit/IOKitLib.h>
#import <CoreFoundation/CoreFoundation.h>

IOHIDDeviceRef device = IOHIDDeviceCreate(kCFAllocatorDefault, deviceService);

IOReturn result = IOHIDDeviceOpen(device, kIOHIDOptionsTypeNone);
if (result != kIOReturnSuccess) {
    // 打开设备失败的处理逻辑
}

CFArrayRef elements = IOHIDDeviceCopyMatchingElements(device, NULL, kIOHIDOptionsTypeNone);
if (elements == NULL) {
    // 获取端点信息失败的处理逻辑
}

for (CFIndex i = 0; i < CFArrayGetCount(elements); i++) {
    IOHIDElementRef element = (IOHIDElementRef)CFArrayGetValueAtIndex(elements, i);
    IOHIDElementType type = IOHIDElementGetType(element);
    if (type == kIOHIDElementTypeOutput) {
        // 找到输出端点的处理逻辑
        break;
    }
}

uint8_t data[] = {0x01, 0x02, 0x03}; // 示例数据
CFIndex dataLength = sizeof(data);

result = IOHIDDeviceSetReport(device, kIOHIDReportTypeOutput, reportID, data, dataLength);
if (result != kIOReturnSuccess) {
    // 写入数据失败的处理逻辑
}

IOHIDDeviceClose(device, kIOHIDOptionsTypeNone);
CFRelease(device);
CFRelease(elements);
