IIS and argv[0] path syntax

Question

I am working on a dll for IIS 5 written in C++ (the webserver of microsoft)

but I see something strange when debugging, in my main() function

argc = 1 and argv[0] = "\\?\C:\Inetpub\wwwroot\Project\Project.dll"

what is this syntax?

It's not exactly easy to search on google !

My code behind, which is also embeded in an executable, was not expecting such a path and is not working anymore.

Answer 1

It's an extended-length path to allow paths of greater length than MAX_PATH.
