Re: PCMCIA /dev nodes

[Germano Leichsenring <germano@jedi.cs.kobe-u.ac.jp>]

Well, I mean devices which can be created with:
mknod /dev/pcmcia0 c 254 0
mknod /dev/pcmcia1 c 254 1
If you make these devices, you can try:

cs_status_t status;
fd = open("/dev/pcmcia1", O_RDONLY);
ioctl(fd, DS_GET_STATUS, &status);

and get the status of the card, there are a couple
of other functions which can be used. The problem is,
if the devices don't exist, the program has to be SUID
to create the node before opening it. I think having
standards /dev/pcmcia? devices would simplify programs
which look at these devices, as they don't have to be
SUID and create the nodes every time (such as /sbin/cardctl).
