1函数定义编辑

HDEVINFO

SetupDiGetClassDevs(

const GUID* ClassGuid,

PCTSTR Enumerator,

HWND hwndParent,

DWORD Flags

);

2参数说明编辑

输入参数：

PGUIDClassGuid

在创建设备列表的时候提供一个指向GUID的指针。如果设定了标志DIGCF_ALLCLASSES，则这个参数可以忽略，且列表结果中包括所有已经安装的设备类别。

PCTSTREnumerator

提供包含设备实例的枚举注册表分支下的键名，可以通过它获取设备信息。如果这个参数没有指定，则要从整个枚举树中获取所有设备实例的设备信息。

HWNDhwndParent

提供顶级窗口的句柄，所有用户接口可以使用它来与成员联系。

DWORDFlags

提供在设备信息结构中使用的控制选项。可以是以下数值：

DIGCF_PRESENT - 只返回当前存在的设备。

DIGCF_ALLCLASSES - 返回所有已安装的设备。如果这个标志设置了，ClassGuid参数将被忽略。

DIGCF_PROFILE - 只返回当前硬件配置文件中的设备。

DIGCF_INTERFACEDEVICE - 返回所有支持的设备。

DIGCF_DEFAULT - 只返回与系统默认设备相关的设备。

3返回值编辑

HDEVINFO

如果函数运行成功，返回设备信息结构的句柄，该结构包含与指定参数匹配的所有已安装设备。如果失败，则返回INVALID_HANDLE_VALUE。调用GetLastError可以获得更多错误信息。

4说明编辑

使用此函数，需要包含头文件setupapi.h。

此外，在project setting中的link页面需要添加setupapi.lib。

在setupapi.h中有如下定义：

typedef PVOID HDEVINFO;

即HDEVINFO是个无类型指针

SetupDiEnumDeviceInfo－使用SetupDi系列函数进行设备信息的管理（二）

BOOLEAN
SetupDiEnumDeviceInfo(
IN HDEVINFO DeviceInfoSet,
IN DWORD MemberIndex,
OUT PSP_DEVINFO_DATA DeviceInfoData
);

SetupDiEnumDeviceInfo 枚举指定设备信息集合的成员，并将数据放在PSP_DEVINFO_DATA中
参数说明：

DeviceInfoSet
提供一个设备信息集合的句柄

MemberIndex
指定一个要取得的设备信息成员序号，从0开始

DeviceInfoData
指向SP_DEVINFO_DATA结构的指针，关于指定成员的返回信息就放在该结构中

Return ValueThe

成功返回True,否则返回False）

如果要枚举全部设备信息成员，装载者首先应该将MemberIndex设为0调用SetupDiEnumDeviceInfo，然后递增MemberIndex（使用一个for循环），调用SetupDiEnumDeviceInfo，直至所有成员全部遍历（此时函数返回False,并且GetLastError返回ERROR_NO_MORE_ITEMS）

SPDRP_CAPABILITIES

The function retrieves a bitwise OR of the following CM_DEVCAP_Xxx flags in a DWORD. The device capabilities that are represented by these flags correspond to the device capabilities that are represented by the members of the DEVICE_CAPABILITIES structure. The CM_DEVCAP_Xxx constants are defined in cfgmgr32.h.

SPDRP_CHARACTERISTICS: The function retrieves a bitwise OR of a device's characteristics flags in a DWORD. For a description of these flags, which are defined in wdm.h and ntddk.h, see the IoCreateDevicefunction's DeviceCharacteristics parameter.
SPDRP_CLASS: The function retrieves a REG_SZ string that contains the device setup class of a device.
SPDRP_CLASSGUID: The function retrieves a REG_SZ string that contains the GUID that represents the device setup class of a device.
SPDRP_COMPATIBLEIDS: The function retrieves a REG_MULTI_SZ string containing the list of compatible IDs for a device. For information about compatible IDs, see Device Identification Strings.
SPDRP_CONFIGFLAGS: The function retrieves a bitwise OR of a device's configuration flags in a DWORD value. The configuration flags are represented by the CONFIGFLAG_Xxx bitmasks that are defined in regstr.h.
SPDRP_DEVICE_POWER_DATA: (Windows XP and later) The function retrieves a CM_POWER_DATA structure containing the device's power management information.
SPDRP_DEVICEDESC: The function retrieves a REG_SZ string containing the description of a device.
SPDRP_DEVTYPE: The function retrieves a DWORD value representing the device's type (see Specifying Device Types).
SPDRP_DRIVER: The function retrieves a string identifying the device's software key (sometimes called the driver key). See Driver Information in the Registry.
SPDRP_ENUMERATOR_NAME: The function retrieves a REG_SZ string containing the name of the device's enumerator.
SPDRP_EXCLUSIVE: The function retrieves a DWORD value that indicates whether a user can obtain exclusive use of the device. The returned value is one if exclusive use is allowed, or zero otherwise. For more information, see IoCreateDevice.
SPDRP_FRIENDLYNAME: The function retrieves a REG_SZ string that contains the friendly name of a device.
SPDRP_HARDWAREID: The function retrieves a REG_MULTI_SZ string containing the list of hardware IDs for a device. For information about hardware IDs, see Device Identification Strings.
SPDRP_INSTALL_STATE: (Windows XP and later) The function retrieves a DWORD value that indicates the installation state of a device. The installation state is represented by one of the CM_INSTALL_STATE_Xxx values that are defined in Cfgmgr32.h.

PropertyBufferSize

The size, in bytes, of the PropertyBuffer buffer.

RequiredSize

A pointer to a variable of type DWORD that receives the required size, in bytes, of thePropertyBuffer buffer that is required to hold the data for the requested property. This parameter is optional and can be NULL.

Return Value

SetupDiGetDeviceRegistryProperty returns TRUE if the call was successful. Otherwise, it returns FALSE and the logged error can be retrieved with a call to GetLastError.SetupDiGetDeviceRegistryProperty returns the ERROR_INVALID_DATA error code if the requested property does not exist for a device or if the property data is not valid.
