This gets the default parameters 73for the open device if no parameters have been set during the session. 74.Pp 75.It Dv FDIOCSETFORMAT Fa struct fdformat_parms 76Set formatting parameters. 77The driver saves this state and it persists while the device is open. 78.Pp 79.It Dv FDIOCFORMAT_TRACK Fa struct fdformat_cmd 80Format a track on the medium. 81If this call returns 82.Er EINVAL , 83the track formatting parameters were out of range for the medium. 84If it returns 85.Er EIO , 86there was a medium error while formatting the track. 87.Pp 88.It Dv FDIOCSETOPTS Fa int 89Set driver options which persist until the device is closed. The 90options should be the logical OR of the desired values below: 91.Pp 92.Bl -tag -width FDOPT_NORETRY -compact 93.It Dv FDOPT_NORETRY 94Do not retry operations on failure 95.It Dv FDOPT_SILENT 96Do not print error messages to the console 97.El 98.Pp 99.It Dv FDIOCGETOPTS Fa int 100Fetch drive options. 101.El 102.Pp 103A typical use of the formatting facilities would be to open the device, 104call 105.Dv FDIOCGETFORMAT 106to fetch the current format parameters, perhaps 107change a parameter or two, display the formatting details to the user, 108and then call 109.Dv FDIOCSETFORMAT 110followed by a series of calls to 111.Dv FDIOCFORMAT_TRACK . 112.Sh SEE ALSO 113.Xr eject 1 , 114.Xr fdformat 1 . 115.Sh BUGS 116Formatting appears to not work reliably on all machines. 117.Sh HISTORY 118The 119.Nm 120formatting support appeared in 121.Nx 1.3 . 122
