C++ Function: List Drive Letters

Write a C++ DLL function to list all the drive letters that are mounted to the same removable device. **Hints:** Everything you need to complete this project is in this Code Project sample: <[login to view URL]> **int GetSameDeviceLetters(WCHAR drv_letter, PWCHAR result_letters);** **Description: **Find all drive letters that are mounted to the same removable device as drv_letter. Save the result in result_letters. Return the number of drive letters saved in the result_letters parameter. result_letters is guaranteed to be at least 52 bytes (26 WCHARs). **Hints: **The Code Project sample above has everything you need to complete this project. The [login to view URL] values are the same for volumes that belong to the same removable device. Here's how to get the InstanceHandle in the Code Project sample. <[login to view URL]> **Example: **As shown in the "Safely Remove Hardware" window below, G: & F: belong to the same USB Mass Storage Device. I: & H: belong to another USB Mass Storage Device. ![][1] Example 1: WCHAR result_letters[26]; int num = GetSameDeviceLetters(L'G', result_letters); After run: num = 2, result_letters = "GF" Example 2: int num = GetSameDeviceLetters(L'F', result_letters); After run: num = 2, result_letters = "GF" Example 3: int num = GetSameDeviceLetters(L'I', result_letters); After run: num = 2, result_letters = "HI" Example 4: int num = GetSameDeviceLetters(L'H', result_letters); After run: num = 2, result_letters = "HI" ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
