Hello,

In C++ or C, is there anyway to detect the name of the module or driver currently used by a network interface card (either wired or wireless, INCLUDING USB DEVICES)?

My application must have this feature. I just want to detect whether the module / driver is ndiswrapper or not.

You could look at the ethtool source for ideas.

EDIT: or you could use something like (my C is rusty) system( "ethtool" "<interface name>" ) and parse the output.

You may scan the output of the last line of any devicesection shows the actually used module.
Or explore the sources of lspci respectively.

Command "ethtool -i <interface name>" really helpful. Thank you! Will look into ethtool's source codes later.

lspci only list the PCI based devices, USB devices will not be listed. That means if my program want to know the name of the driver used by my USB Network Interface Card, using lspci is impossible. However, I still appreciate for your reply.

Anyway, I still hope for more ideas. Anyone with any other ideas, or if anyone can suggest a library or give me sample codes, please feel free to reply here. Any replies, whether helpful or not, will be appreciated.

lsusb lists the USB hardware but not the associated drivers. For more info (but still not but not the associated drivers) use its -v option. Given information from lsusb, the kernel messages in /var/log/messages (system dependent?) should (TM) reveal which driver is loaded for each USB device but this is non-trivial and not the best way of doing it programmatically.
