| 释义 | RegisterRawInputDevices 语法： BOOL RegisterRawInputDevices( PCRAWINPUTDEVICE pRawInputDevices, UINT uiNumDevices, UINT cbSize ); RegisterRawInputDevices功能 该RegisterRawInputDevices函数注册的设备，供应的原始输入数据。 参数 pRawInputDevices [in]指向一个RAWINPUTDEVICE结构的数组代表的设备的供应原料投入。 uiNumDevices [in]的RAWINPUTDEVICE结构的数目指向pRawInputDevices。 cbSize [中]大小，以字节为单位，一个RAWINPUTDEVICE结构。 返回值 TRUE，如果函数成功，否则，假。如果函数失败更多的信息，调用GetLastError。 备注 要接收WM_INPUT消息，应用程序必须先注册的原始输入设备使用RegisterRawInputDevices。默认情况下，应用程序不接收原始的输入。 如果RAWINPUTDEVICE结构对RIDEV_REMOVE标志设置和hwndTarget参数没有设置为NULL，然后参数验证将失败。 功能信息 最低DLL版本 user32.dll 在Winuser.h中HeaderDeclared，头文件：winuser.h import libraryUser32.lib XP的最低经营systemsWindows 参见 原始输入，RAWINPUTDEVICE，WM_INPUT ＝＝英文原文＝＝RegisterRawInputDevices Function The RegisterRawInputDevices function registers the devices that supply the raw input data. Syntax BOOL RegisterRawInputDevices( PCRAWINPUTDEVICE pRawInputDevices, UINT uiNumDevices, UINT cbSize ); Parameters pRawInputDevices [in] Pointer to an array of RAWINPUTDEVICE structures that represent the devices that supply the raw input. uiNumDevices [in] Number of RAWINPUTDEVICE structures pointed to by pRawInputDevices. cbSize [in] Size, in bytes, of a RAWINPUTDEVICE structure. Return Value TRUE if the function succeeds; otherwise, FALSE. If the function fails, call GetLastError for more information. Remarks To receive WM_INPUT messages, an application must first register the raw input devices using RegisterRawInputDevices. By default, an application does not receive raw input. If a RAWINPUTDEVICE structure has the RIDEV_REMOVE flag set and the hwndTarget parameter is not set to NULL, then parameter validation will fail.
