[RESOLVED] Get comm num from handle?

[wolf99]

Hi again folks.

Is there a way in C of getting the comm port number if I have a handle of said comm port?

obviously I already know the comm number (thats how I got the handle in the first place) but I am using multiple ports and dont want to have to go passing the different numbers around along with the handles, especially when it essentially only going to lead to a more concise error message.

Thanks

What about the GetCommProperties function? I'm guessing you are getting the handle via the CreateFile function?

Actually you might even be able to use the GetFileInformationByHandle function.
