wireless device?

Im trying to figure out what device file, "/dev/??" my wireless card
is? I am using slack 10.2 with the 2.16.13 kernel, and the host AP
driver. Any info will help.
Thanks,
Jimi

WLAN is a network interface.

The network interfaces live in a name space totally different
from the file naming tree, so there are no /dev files for them.

You can access the network interfaces from code by creating a
network socket and using suitable ioctl() calls to it.

From the console, the tool is ifconfig. Try

ifconfig -a

and have a look if it shows the informatio you're looking for.

ahso, ahso. So how do you refer to to wlan with the ioctl function.

You create a network socket and use the returned
handle for ioctl() calls on that socket.

For a detailed discussion, get the book

W. Richard Stevens, Unix network Programming,
Volume 1, Second Edition: Networking APIs: Sockets and XTI,
Prentice-Hall, ISBN ISBN 0-13-490012-X.

For man pages, you could start at

man 7 ip

aight aight, Iv'e heard Stevens books are very good.

Thanks you,

Also note:
I am not tyring to talk to a server, I am trying to access functions
that are on the built into the wireless card.

The authoritative response comes from the WLAN driver
sources: Look which ioctl's it supports.

The connection between iwconfig nad the WLAN card
internal functions is with the ioctl interface.

Tauno,
I have some questions, that are kind of sensititve, I was wondering if
I could email you.
Just to give you an idea of what i need to do; i am trying to make a
certain wireless card work with the hostAP drivers. The card is meant
to work with the wlan-ng-2.0 driver which are old and no longer
updated. To give you an idea of what I have done so far; I edited the
/etc/pcmcia/host_cs.conf file with the information the card firmware
gives you, when you do a "cardtrl ident", but when the is inserted, it
looks as if its not getting any power, the card lights up for about a 1
second then, all of the lights go out.

You can email me at: barnetj1 at cs.sunyit.edu

Thanks,
Jimmie

A quick question: Has the card ever behaved with any
WLAN drivers in your Linux?

The WLAN card makers are notorious in marking the cards
with the same make and model, but with different innards.

I once fought with some SMC cards before I understood
that version 1, version 2 and version 3 of the same card
have totally different innards: the chipsets were not even
from the same manufacturer.

You can mail me: Clean the address in the sig in an obvious way.

No not on my current system, I have seen the card light up on a
different system, running red hat with the 2.4.x kernel, it was also
using the wlan-ng-2.0 driver too. Laso note when i do a cardctl insert
i get this message in the syslog..

dhcpStart: interface wifi0 is not Ethernet or 802.2 Token Ring

Thanks for your help,
