Description
The documentation of CreatePseudoConsole explicitly documents that CreatePseudoConsole can be used with sockets:
If we look at the implementation of CreatePseudoConsole, we can see it calls DuplicateHandle on the handles passed to it:
However, the documentation of DuplicateHandle explicitly mentions that DuplicateHandle should not be used to duplicate socket handles:
https://docs.microsoft.com/en-us/windows/win32/api/handleapi/nf-handleapi-duplicatehandle#remarks
Doesn't this make the CreatePseudoConsole implementation incorrect when using sockets?
I haven't actually confirmed whether sockets work or not, I'm currently trying to get CreatePseudoConsole to work with sockets but it's returning Access is Denied. While looking at the source code to figure out why it's returning Access is Denied, I stumbled upon this possible issue.
EDIT: Nvm the Access is Denied issue, I incorrectly assumed CreatePseudoConsole would return 0 on failure. The DuplicateHandle issue still stands however.
EDIT2: Removed edit because it was a programming error by me.
