C# Signature:

[DllImport("psapi")]
private static extern int GetDeviceDriverBaseName(
    UInt32 ddAddress,
    StringBuilder ddBaseName,
    int baseNameStringSizeChars
);

VB Signature:

Declare Function GetDeviceDriverBaseName Lib "psapi.dll" (TODO) As TODO

User-Defined Types:

None.

Alternative Managed API:

Do you know one? Please contribute it!

Notes:

This function takes a 'load address' that needs to be obtained from EnumDeviceDrivers.

Tips & Tricks:

Please add some!

Sample Code:

using System;
using System.Runtime.InteropServices;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace EnumDriversTest
{
    class Program {
        [DllImport("psapi")]
        private static extern bool EnumDeviceDrivers(
            [MarshalAs(UnmanagedType.LPArray, ArraySubType = UnmanagedType.U4)] [In][Out] UInt32[] ddAddresses,
            UInt32 arraySizeBytes,
            [MarshalAs(UnmanagedType.U4)] out UInt32 bytesNeeded
        );

        [DllImport("psapi")]
        private static extern int GetDeviceDriverBaseName(
            UInt32 ddAddress,
            StringBuilder ddBaseName,
            int baseNameStringSizeChars
        );

        static void Main(string[] args) {
            UInt32 arraySize;
            UInt32 arraySizeBytes;
            UInt32[] ddAddresses;
            UInt32 bytesNeeded;
            bool success;

            // Figure out how large an array we need to hold the device driver 'load addresses'
            success = EnumDeviceDrivers(null, 0, out bytesNeeded);

            Console.WriteLine("Success? " + success);
            Console.WriteLine("Array bytes needed? " + bytesNeeded);

            if (!success) {
                Console.WriteLine("Call to EnumDeviceDrivers failed!  To get extended error information, call GetLastError.");
                return;
            }
            if (bytesNeeded == 0) {
                Console.WriteLine("Apparently, there were NO device drivers to enumerate.  Strange.");
                return;
            }

            // Allocate the array; as each ID is a 4-byte int, it should be 1/4th the size of bytesNeeded
            arraySize = bytesNeeded / 4;
            arraySizeBytes = bytesNeeded;
            ddAddresses = new UInt32[arraySize];

            // Now fill it
            success = EnumDeviceDrivers(ddAddresses, arraySizeBytes, out bytesNeeded);

            if (!success) {
                Console.WriteLine("Call to EnumDeviceDrivers failed!  To get extended error information, call GetLastError.");
                return;
            }

            for (int i=0; i < arraySize; i++) {
                // If the length of the device driver base name is over 1000 characters, good luck to it.  :-)
                StringBuilder sb = new StringBuilder(1000);

                int result = GetDeviceDriverBaseName(ddAddresses[i], sb, sb.Capacity);

                Console.WriteLine("Device driver LoadAddress: " + ddAddresses[i] + ", BaseName: " + sb.ToString());
            }
        }
    }
