|Hi Amancio Hasty,
|I have a C programe written by you from
|www.freebsd.org/~ahasty/files/videocapture.c
Gee Amancio. It's your code.
Minlin, let me see what I can see. I'll take a second and give it a shot.
First, a very small nit. Please turn off the HTML-mailing feature in the
Linux Netscape 4.05 you are running. It obfuscates the message, and the
mail takes "alot longer" to POP across for folks with dial-up connections:
|<P> i = 112;
|<BR> if (ioctl(bt848, METEORSCONT,
|&i) < 0) {
|<BR>
|
|1. The " sig_t done" and " sig_t do_write" generate error in
|compile-time.
No idea on this one.
|2. I comment out these lines regarding " sig_t ". The compiling is
|successful. But there are run-time errors in
...
| if (ioctl(bt848, METEORSCONT, &i) < 0) {
...
| if (ioctl(bt848, METEORSBRIG, &i) < 0) {
...
| if (ioctl(bt848, METEORSETGEO, &geo) < 0) {
...
|Please help me and concentrate on the second problem. Because I got the
|same problem in other similar program.
|Thank you very much.
First question? Do you have a meteor, and do you have the meteor0 device
compiled into your kernel? If yes to the first, I'm guessing no to the
second.
If you have a BT848 (bktr) card, in Bt848-land (see
/usr/include/machine/ioctl_bt848.h), the first two should instead be
BT848_SCONT, BT848_SBRIG, and they should be issued to the tuner file
descriptor (/dev/tuner#). The METEORSETGEO is used in Bt848-land though,
and is issued to the Bt848 file descriptor (/dev/bktr#).
You need both of these for Bt848 code:
#include <machine/ioctl_meteor.h>
#include <machine/ioctl_bt848.h>
For meteor code, presumably just the first and the symbols that are
described in the file you quoted above.
