标签： windows winapi

Windows API函数GetRawInputDeviceInfo具有参数uiCommand。其中一个选项是RIDI_PREPARSEDDATA。它说“pData指向先前解析的数据”。

我没有得到他们之前解析的数据。它是上次与WM_INPUT一起发送的数据吗？或者它是由任何函数返回的数据？或者是其他东西？该数据的格式是什么？

预准备数据是与顶级集合关联的报表描述符数据。用户模式应用程序或内核模式驱动程序使用预先准备的数据来提取有关特定HID控件的信息，而无需获取和解释设备的整个报表描述符。

“该数据的格式是什么？”

今天我研究了GetRawInputDeviceInfo（），包括RIDI_PREPARSEDDATA数据。这是测试我的XBOX控制器时程序的输出。除可显示字符外的所有内容均为十六进制，可显示字符的十六进制在可显示字符后的括号中给出。

注意开头的HidP KDR。除此之外，它看起来像胡言乱语。该程序很好地将其格式化为四个八位字，但看起来如果没有我的额外努力，它将无法正常显示。是的，它意味着在命令行上显示，不，我不想摆脱系统的结果（“暂停”）。
