NAME
fdio - floppy disk control operations
SYNOPSIS
#include <sys/fdio.h>
-
DESCRIPTION
! The Solaris floppy driver supports a set of ioctl(2) requests for
! getting and setting the floppy drive characteristics. Basic to these
! ioctl() requests are the definitions in <sys/fdio.h>.
IOCTLS
! The following ioctl() requests are available on the Solaris floppy
driver.
! FDDEFGEOCHAR
! x86 based systems: This ioctl() forces the floppy
! driver to restore the diskette and drive
! characteristics and geometry, and partition information
! to default values based on the device configuration.
- FDGETCHANGE
- The argument is a pointer to an int. This ioctl()
- returns the status of the diskette-changed signal from
- the floppy interface. The following defines are
- provided for cohesion.
-
-
-
Note: For x86 based systems, use FDGC_DETECTED (which is available only
on x86 based systems) instead of FDGC_HISTORY.
/*
* Used by FDGETCHANGE, returned state of the sense disk change bit.
*/
! #define FDGC_HISTORY 0x01 /* disk has changed since insertion or
! last FDGETCHANGE call */
! #define FDGC_CURRENT 0x02 /* if set, indicates drive has floppy,
! > otherwise, drive is empty */
#define FDGC_CURWPROT 0x10 /* current state of write protect */
#define FDGC_DETECTED 0x20 /* previous state of DISK CHANGE */
! FDIOGCHAR
! The argument is a pointer to an fd_char structure
! (described below). This ioctl() gets the characteristics
! of the floppy diskette from the floppy controller.
!
! FDIOSCHAR
! The argument is a pointer to an fd_char structure
! (described below). This ioctl() sets the characteristics
! of the floppy diskette for the floppy controller. Typical
! values in the fd_char structure for a high density
! diskette:
!
! field value
fdc_medium 0
fdc_transfer_rate 500
fdc_ncyl 80
fdc_nhead 2
fdc_sec_size 512
fdc_secptrack 18
