Detect if USB disk is mounted or not in C application in Linux
I would like to check if USB disk is mounted or not in a C application. I know that in a script I can accomplish this via mount | grep /mnt (the mount point where udev mounts the USB drive) but I need to do this in a C application. Earlier I used to accomplish this using system("sh script.sh") but doing this is causing some serious issues as this code runs in a very time critical thread. Please help advise on the best possible way to do this.
Thanks

you're not telling what system you're using; on Linux you have all the info you need in the/proc/self/mountinfofile, which you can read with fgets/sscanf. see the procfs(5) manpage.

Sorry. Added that this is required for a Linux application

then go on and read/proc/self/mountinfo-- that's whatfindmnt(8)is doing, too.
