If the device is not a CD-ROM, 109or the table of contents cannot be examined, the file system will be 110started at sector 0. This option can be used to override the behaviour. 111Note that 112.Ar startsector 113is measured in CD-ROM blocks, with 2048 bytes each. This is the same 114as for example the 115.Cm info 116command of 117.Xr cdcontrol 1 118is printing. 119It is possible to mount an arbitrary session of a multi-session CD by specifying 120the correct 121.Ar startsector 122here. 123.It Fl C Ar charset 124Specify local 125.Ar charset 126to convert Unicode file names when using Joliet extensions. 127.It Fl v 128Be verbose about the starting sector decisions made. 129.El 130.Sh EXAMPLES 131The following command can be used to mount a Kodak Photo-CD: 132.Pp 133.Dl "mount_cd9660 -o rw -v -s 0 /dev/cd0c /cdrom" 134.Sh SEE ALSO 135.Xr cdcontrol 1 , 136.Xr mount 2 , 137.Xr unmount 2 , 138.Xr fstab 5 , 139.Xr mount 8 140.Sh BUGS 141POSIX device node mapping is currently not supported. 142.Pp 143Version numbers are not stripped if Rockridge extensions are in use. 144In this case, accessing files that don't have Rockridge names without 145version numbers gets the one with the lowest version number and not 146the one with the highest. 147.Pp 148There is no ECMA support. 149.Sh HISTORY 150The 151.Nm 152utility first appeared in 153.Bx 4.4 . 154.Pp 155The Unicode conversion routine was added by 156.An Ryuichiro Imura Aq imura@ryu16.org 157in 2003. 158
