Windows下获取设备管理器列表信息-setupAPI
背景及问题：在与硬件打交道时，经常需要知道当前设备连接的硬件信息，以便连接正确的硬件，比如串口通讯查询连接的硬件及端口，一般手工的方式就是去设备管理器查看相应的信息，应用程序如何读取这一部分信息呢，Windows下的SetupAPI系列就可以解决这个问题示例程序
#include#include#include#include#pragma comment(lib, "setupapi.lib")int main(){ //set chinese character std::locale::global(std::locale("")); //The SetupDiGetClassDevs function returns a handle to a device //information set that contains requested device information //elements for a local computer. HDEVINFO hdevinfo = SetupDiGetClassDevs(NULL, NULL, NULL, DIGCF_PRESENT | DIGCF_ALLCLASSES); if (hdevinfo != INVALID_HANDLE_VALUE) { DWORD MemberIndex = 0; SP_DEVINFO_DATA sp_devinfo_data; ZeroMemory(&sp_devinfo_data, sizeof(sp_devinfo_data)); sp_devinfo_data.cbSize = sizeof(sp_devinfo_data); //The SetupDiEnumDeviceInfo function returns a SP_DEVINFO_DATA //structure that specifies a device information element in a //device information set. while (SetupDiEnumDeviceInfo(hdevinfo, MemberIndex, &sp_devinfo_data)) { TCHAR PropertyBuffer; //The SetupDiGetDeviceRegistryProperty function retrieves //a specified Plug and Play device property. if (SetupDiGetDeviceRegistryProperty(hdevinfo, &sp_devinfo_data, SPDRP_DEVICEDESC, NULL, (PBYTE)&PropertyBuffer, sizeof(PropertyBuffer), NULL)) { std::wcout
