Hi,
I need to be able to open a device using the POSIX reference in Cygwin
and issue IOCTL calls to it. SCSI commands specifically.
The following is some code:
struct sg_io_hdr io_hdr;
int fd = open("/dev/sdc", O_RDWR);
ret = ioctl(fd, SG_IO, &io_hdr);
I put in my own sg_io_hdr in the file which I copied from the sg.h.
I had return code = -1 which is error.
Could someone please give me some ideas about how to do this right.
Thanks.
Lihong
