Hi,
I had a device (disk on key) and I try to send Inquiry command to the device
and then to get response from device.
My problem is I can not understand the buffer(o_buff) that came from my
device.
This is my code:
#define SCSI_OFF sizeof(struct sg_header)
/***************************************************************************
****************/
sg_hd = (struct sg_header *) i_buff;
sg_hd->reply_len = SCSI_OFF + out_size;
sg_hd->twelve_byte = (cmd_len ==12);
sg_hd->result = 0;
/* send command */
status = write( fd[numOfDev], i_buff, SCSI_OFF + cmd_len + in_size );
if ( status < 0 || status != SCSI_OFF + cmd_len + in_size ||
sg_hd->result )
{
// some error happened
fprintf( stderr, "write(generic) result = 0x%x cmd = 0x%x\n",
sg_hd->result, i_buff[SCSI_OFF] );
printf("device num: %d ,write NO OK\n",numOfDev);
return status;
}
else
printf("OK\n");
/* retrieve result */
status = read( fd[numOfDev], o_buff, SCSI_OFF + out_size);
/***************************************************************************
****************/
When I try to print my o_buff (after read() operation ) I got something that
I can not understand.
I believe I had mistake with my write() function.
What should I eneter in i_buff ???
thanks,
eyalz
