Hi All,
I am a application developer on Linux.
Currently I am working on an USB application where I need to check
whether the device is connected or not.
Description:
Linux kernel version 2.4
Whenever a USB device is getting connected, hotplug will recognize this
and mount it on to a mount point "/mnt/usb"
Application will know only "/mnt/usb" as the device.
Suddenly if the user unplug the device without unmounting the device ,
the mount point will still remain in the system.
Later whenever application access this mount point (through statvfs()
call) , the operation will be success even though the device is not
connected.
Please let me know is there any other way of verifying the USB device
existence by using the mount point ("/mnt/usb") as my application will
have only this info.
Thanks In Advance,
Narendra Babu H.C.
