Subject: fd type from number
Date: Mon, 18 Aug 2014 17:46:16 -0700	[thread overview]
Message-ID: <53F29E58.5060202@draios.com> (raw)
In-Reply-To: <CAPDOMVirn+wtoKBTTywsCEs8K-iKBg6wBz-z6Q7-zMWPTHsZRw@mail.gmail.com>

I'm looking for an efficient way to determine the type of an fd (file, 
socket...) given its number, from a kernel module.
The closest thing I found by looking at the kernel sources is 
sockfd_lookup(), which works but is limited to telling me if the fd is a 
socket or not.

Is there something else I can look at?

Thank you in advance,
Loris
