Converting DriverVersion to Human readable format - c++

Question

I have searched high and low for it, could not find any documentation, I am able to get the DriverVersion as described Here. Creating and enumerating the device drives is working so there is no need to look there. The DriverVersion is a type of "DWORDLONG". I need to convert this to Human readable format like 20.xx.xx.xx. There ain't any documentation on MSDN, or anywhere I have searched.
Any help will be appreciated.
Example value of "DriverVersion" : 1688863374327808
Code snippet, if at all its required,
SP_DEVINFO_DATA devInfo;
devInfo.cbSize = sizeof(SP_DEVINFO_DATA);
if (SetupDiEnumDeviceInfo(handle, 0, &devInfo))
{
if(SetupDiBuildDriverInfoList(handle,&devInfo,SPDIT_COMPATDRIVER))
{
SP_DRVINFO_DATA drvInfo;
drvInfo.cbSize = sizeof(SP_DRVINFO_DATA);
int i=0;
while(1)
{
try
{
if (SetupDiEnumDriverInfo(handle, &devInfo, SPDIT_COMPATDRIVER, i++, &drvInfo))
{
cout<<"Version :"<<drvInfo.DriverVersion<<endl; // Need Human Readable version here.
}
else
break;
}
catch(std::exception ex)
{
break;
}
}
}
}

You could use a ULARGE_INTEGER union, the HIWORD/LOWORD macros and string formatting utils like boost::format to do the following (untested code):
SP_DRVINFO_DATA driverInfoData;
ULARGE_INTEGER version;
version.QuadPart = driverInfoData.DriverVersion;
std::string versionStr = (boost::format("%s.%s.%s.%s")
% HIWORD(version.HighPart)
% LOWORD(version.HighPart)
% HIWORD(version.LowPart)
% LOWORD(version.LowPart)).str();
Following your code and to get rid of boost simply do:
std::cout << "Version: "
<< std::to_string(HIWORD(version.HighPart)) << "."
<< std::to_string(LOWORD(version.HighPart)) << "."
<< std::to_string(HIWORD(version.LowPart)) << "."
<< std::to_string(LOWORD(version.LowPart)) << std::endl;
