Detect storage device by checking mounted file system to Linux


Is there any API to detect file system information in a host. I mean, if a host contains hard disk, USB pen drive and a SD Card connected via PCMCIA slot, is it possible to check if file systems of these storage devices are mounted to the OS?

statfs or fstatfs requires file name or file descriptor as pre-requisite, what about if we do not know any file in these devices, but would like to check what kind of storage device is attached to the host by checking file system mounted to it

If I get you right, then ...
without parameters will give you information about mounted devices and filesystems
df -h
will give you info about sizes of mounted devices in human readable (-h) format (that is with appended M for Megabytes and G for Gigabytes

See getmntent(3) You may use it on /etc/mtab (and perhaps /proc/mounts too)

You can find a file system by label or uuid with findfs. It isn't always accurate though, and I'm not sure how it works over a network.
