Windows programming: Traversing the dynamic-link library (DLL) code used by the program (C + +)

Traversing the dynamic-link library (DLL) used by the program first requires traversing all processes, matching the process name with the process ID, and then outputting all the libraries (DLLs) that are used according to the process name.

In the example, Image.exe is a pre-boot program. The code contains code to traverse the process, and to output dynamic-link libraries (DLLs).

Code:
