Hi Amancio Hasty,
I have a C programe written by you from
www.freebsd.org/~ahasty/files/videocapture.c
I got two problems:
1. The " sig_t done" and " sig_t do_write" generate error in
compile-time.
Here are the compile-time errors:
videocapture.c:84: parse error before `done'
videocapture.c:141: parse error before `do_write'
videocapture.c: In function `main':
videocapture.c:247: `sig_t' undeclared (first use this function)
videocapture.c:247: (Each undeclared identifier is reported only
once
videocapture.c:247: for each function it appears in.)
videocapture.c:247: parse error before `done'
2. I comment out these lines regarding " sig_t ". The compiling is
successful. But there are run-time errors in
the following codes:
i = 112;
if (ioctl(bt848, METEORSCONT, &i) < 0) {
fprintf(stderr, "ioctl failed: %s\n", strerror(errno));
exit(0);
}
i = 0x30;
if (ioctl(bt848, METEORSBRIG, &i) < 0) {
fprintf(stderr, "ioctl failed: %s\n", strerror(errno));
exit(0);
}
if (ioctl(bt848, METEORSETGEO, &geo) < 0) {
printf("ioctl failed: %d\n", errno);
exit(1);
}
Please help me and concentrate on the second problem. Because I got the
same problem in other similar program.
Thank you very much.
