I'm trying to do some capacity testing of the hardware and we have a FDDI
device with a device id (shown in the admin tools) as fta0. I need to
determine if the interface used can provide the necessary file descriptors
required in our application. I want to write some code based on opening a
raw device -- 'open(devicename, O_WRONLY)' -- but I can't find the device
name in the /dev directory or anywhere else on the system. I've found a
reference to fta0 in rc.config and the device is working normally on our
network.
I'm new to the Digital Unix world and it seems the term "device" seems to
be used exclusively in the context of ttys or storage devices (e.g., disks,
floppys, CD ROMs).
In the other Unixes I've worked with a new device is created and locatable
in the /dev directory. In AIX, when I opened the FDDI device, I needed add
the driver to the call -- open("/dev/dlcfddi/fi0", O_WRONLY).
