GetProductInfo - pdwReturnedProductType Meaning (The product type)?

The GetProductInfo function is a Windows API function used to retrieve information about the operating system version and the installed product type. The function returns information in several output parameters, including the pdwReturnedProductType parameter, which represents the product type of the operating system.

The pdwReturnedProductType parameter is a pointer to a variable that will receive the product type information. The possible values for the pdwReturnedProductType parameter are defined as constants in the winnt.h header file and are as follows:

• PRODUCT_UNDEFINED: The product type cannot be determined.
• PRODUCT_ULTIMATE: Windows 7 Ultimate edition.
• PRODUCT_HOME_BASIC: Windows 7 Home Basic edition.
• PRODUCT_HOME_PREMIUM: Windows 7 Home Premium edition.
• PRODUCT_ENTERPRISE: Windows 7 Enterprise edition.
• PRODUCT_HOME_BASIC_N: Windows 7 Home Basic N edition.
• PRODUCT_BUSINESS: Windows 7 Business edition.
• PRODUCT_STANDARD_SERVER: Windows Server 2008 Standard edition.
• PRODUCT_DATACENTER_SERVER: Windows Server 2008 Datacenter edition.
• PRODUCT_ENTERPRISE_SERVER: Windows Server 2008 Enterprise edition.
• ... and more

Please note that these values are specific to Windows operating systems and versions. The pdwReturnedProductType value can be used to determine the edition or type of the operating system on which the application is running. This information can be useful for adapting the behavior of your application based on the capabilities or limitations of the operating system version.

Here's a basic example of how the GetProductInfo function might be used:

cCopy code
#include <Windows.h>

#include <WinNT.h>



int main() {

    DWORD productType = 0;

    GetProductInfo(GetVersion(), 0, 0, 0, &productType);

    

    switch (productType) {

        case PRODUCT_ULTIMATE:

            printf("Windows 7 Ultimate Edition\n");

            break;

        case PRODUCT_HOME_BASIC:

            printf("Windows 7 Home Basic Edition\n");

            break;

        // ... other cases ...

        default:

            printf("Unknown product type\n");

            break;

    }



    return 0;

}

Keep in mind that Windows APIs may change over time with new versions of the operating system. Always refer to the official Microsoft documentation for the most accurate and up-to-date information about API functions and their parameters.
