[ilugd] How to execute open & ioctl in User mode?

[Sunil S]

Hi everyone,
    Is there any way by which one can use the 'open' system call in a program to 
access the device file descriptor in user mode? For  example

......
.....
int fd = open('/dev/scsi', _RONLY);
if (fd != -1) 
{
   printf("Error");

}
else
{ 
   int handle;
   ioctl(fd,SCSI_IOCTL_GET_BUS_NO, &handle);
   ..........
   ..........
}
........
......
the above piece of code works well when executed with root user.

Is there any way by which you can execute the program in user mode.

Regards,
Sunil
