My objective is to determine the name of a mounted USB flash drive programmatically in linux using C.
Has anyone got any suggestions?

What do you mean with _the name of detected USB flash drive_? – LPs Dec 26 '16 at 09:06

I mean the display name, the name of the device that I specify when I format it – Kallel Omar Dec 26 '16 at 09:15

You do not format a disk but rather a partition (aka volume). The name you assign to it after formatting is called a *volume label*. To query the volume label you do not use any `USB` API but rather file system API. – Alex P. Dec 26 '16 at 23:49

you can use the command: `lsusb -v -t` to determine where the device is mounted, Then pass that address as a parameter to your program – user3629249 Dec 27 '16 at 05:36

think the USB stick is registered as /dev/sdb (you can determine which is the USB stick in /dev using sudo fdisk -l or dmesg with tail and grep)
if you want to get the label of the USB stick you can use sudo mlabel -i /dev/sdb1 -s :: and then extract the label using grep, awk or sed

if you want to get the UUID you can use sudo blkid /dev/sdb1
