fdio(7I) Ioctl Requests SunOS 5.5
FDEJECT SPARC: This ioctl() requests the floppy drive to eject the diskette.
FDIOCMD The argument is a pointer to an fd_cmd structure (described below).
This ioctl() allows access to the floppy diskette using the floppy device
driver. Only the FDCMD_WRITE, FDCMD_READ, and
FDCMD_FORMAT_TR commands are currently available.
struct fd_cmd {
u_short fdc_cmd; /∗ command to be executed ∗/
int fdc_flags; /∗ execution flags (x86 only) ∗/
daddr_t fdc_blkno; /∗ disk address for command ∗/
int fdc_secnt; /∗ sector count for command ∗/
caddr_t fdc_bufaddr; /∗ user’s buffer address ∗/
u_int fdc_buflen; /∗ size of user’s buffer ∗/
};

#define FDCMD_REZERO 4
#define FDCMD_FORMAT_UNIT 5
#define FDCMD_FORMAT_TRACK 6
FDRAW The argument is a pointer to an fd_raw structure (described below).
This ioctl() allows direct control of the floppy drive using the floppy
controller. Refer to the appropriate floppy-controller data sheet for full
details on required command bytes and returned result bytes. The fol-
lowing commands are supported.
