ddk 库和头文件 驱动开发

用过GPRS/CDMA Modem的都知道，要首先添加驱动(比如你要添加一个33600的标准调制解调器)，手动添加当然是可以的，但是比较麻烦，而且不熟悉的人可能会出错，如果知道调用哪个API函数，用程序实现这个功能是非常理想的。安装驱动的API函数，都包含在cfgmgr32.dll，setupapi.dll，newdev.dll这几个动态链接库里。当时VC6.0开发时，由于对这些API函数不太熟悉，所以就想到显示调用这些dll。于是我安装了WIN2K DDK，（我的操作系统是2000），DDK里有这些DLL的头文件和库引导文件，在VC6.0的包含路径里，include files和 library files，把DDK的头文件和库文件包含进去，注意，要放在首位。这样就可以使用SetupDiGetClassDevs这些函数了。以下是主要源码 #include "stdafx.h" #include <tchar.h> // Make all functions UNICODE safe. #include <newdev.h> // for the API UpdateDriverForPlugAndPlayDevices(). #include <setupapi.h> // for SetupDiXxx functions. #include "install.h" int DisplayError(TCHAR * ErrorName) { DWORD Err = GetLastError(); LPVOID lpMessageBuffer = NULL; if (FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, NULL, Err, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &lpMessageBuffer, 0, NULL )) NULL; //_tprintf(TEXT("%s FAILURE: %s\n"),ErrorName,(TCHAR *)lpMessageBuffer); else NULL; //_tprintf(TEXT("%s FAILURE: (0x%08x)\n"),ErrorName,Err); if (lpMessageBuffer) LocalFree( lpMessageBuffer ); // Free system buffer SetLastError(Err); return FALSE; } BOOL FindExistingDevice(IN LPTSTR HardwareId) //查找是否存在改硬件ID { HDEVINFO DeviceInfoSet; SP_DEVINFO_DATA DeviceInfoData; DWORD i,err; BOOL Found; // // Create a Device Information Set with all present devices. // DeviceInfoSet = SetupDiGetClassDevs(NULL, 0, 0,DIGCF_ALLCLASSES | DIGCF_PRESENT ); // All devices present on system if (DeviceInfoSet == INVALID_HANDLE_VALUE) { return DisplayError(TEXT("GetClassDevs(All Present Devices)")); } //_tprintf(TEXT("Search for Device ID: [%s]\n"),HardwareId); // // Enumerate through all Devices. // Found = FALSE; DeviceInfoData.cbSize = sizeof(SP_DEVINFO_DATA); for (i=0;SetupDiEnumDeviceInfo(DeviceInfoSet,i,&DeviceInfoData);i++) { DWORD DataT; LPTSTR p,buffer = NULL; DWORD buffersize = 0; // // We won't know the size of the HardwareID buffer until we call // this function. So call it with a null to begin with, and then // use the required buffer size to Alloc the nessicary space. // Keep calling we have success or an unknown failure. // while (!SetupDiGetDeviceRegistryProperty( DeviceInfoSet, &DeviceInfoData, SPDRP_HARDWAREID, &DataT, (PBYTE)buffer, buffersize, &buffersize)) { if (GetLastError() == ERROR_INVALID_DATA) { // // May be a Legacy Device with no HardwareID.
