To guard a process, you must first know that the process is absent. We assume that only one instance exists for the process to be guarded (this is also the case in most cases ).

I traverse all the processes on the system, and then determine whether their paths are consistent with those of the processes to be guarded, so as to determine whether the process exists.

We all know that the createconlhelp32snapshot series APIs are used for Traversing processes. But what they get is the process exe name, not the full path. If they only rely on the name, they can achieve the goal, but sometimes you still need to get the full path, which will be more reliable.

So the question is, how can we get the full process path?

The first appearance is GetModuleFileNameEx. Most of the time, we can use this function to obtain the full path of the process, and this function is available in all platforms, but have you noticed the following:
