.SH DESCRIPTION
.sp
.LP
\fBmount\fR attaches an \fBMS-DOS\fR file system (\fBpcfs\fR) to the file
system hierarchy at the \fImount_point\fR, which is the pathname of a
directory. If \fImount_point\fR has any contents prior to the \fBmount\fR
operation, these are hidden until the file system is unmounted.
.sp
.LP
The \fBpcfs\fR file system supports direct mounting of files containing the
file system as well as block devices. See \fBmount\fR(1M) and
\fBlofiadm\fR(1M).
.sp
.LP
If \fBmount\fR is invoked with \fIspecial\fR or \fImount_point\fR as the only
arguments, \fBmount\fR will search \fB/etc/vfstab\fR to fill in the missing
arguments, including the \fIFSType-specific_options\fR; see \fBmount\fR(1M) for
more details.
.sp
.LP
The \fIspecial\fR argument can be one of two special device file types:
.RS +4
.TP
.ie t \(bu
.el o
A floppy disk, such as \fB/dev/diskette0\fR or \fB/dev/diskette1\fR.
.RE
.RS +4
.TP
.ie t \(bu
.el o
A DOS logical drive on a hard disk expressed as
\fIdevice-name\fR\fB:\fR\fIlogical-drive\fR , where \fIdevice-name\fR specifies
the special block device-file for the whole disk and \fIlogical-drive\fR is
either a drive letter (c through z) or a drive number (1 through 24). Examples
are \fB/dev/dsk/c0t0d0p0:\fR\fIc\fR and \fB/dev/dsk/c0t0d0p0:\fR\fI1\fR.
.RE
.sp
.LP
The \fIspecial\fR device file type must have a formatted \fBMS-DOS\fR file
system with either a 12-bit, 16-bit, or 32-bit File Allocation Table.
.SH OPTIONS

See \fBmount\fR(1M) for the list of supported options.

.sp

.na
\fB\fB-o\fR\fR
.ad
.sp .6
.RS 4n
Specify \fBpcfs\fR file system-specific options. The following options are
supported:
.sp
.ne 2
.na
\fB\fBclamptime\fR | \fBnoclamptime\fR\fR
.ad
.sp .6
.RS 4n
File timestamps in \fBpcfs\fR cover a range between January 1st 1980 and
December 31st 2127. This is not equal to the range of \fBtime_t\fR on Unix for
either 32-bit or 64-bit applications. In particular, 32-bit applications fail
with \fBEOVERFLOW\fR errors on the \fBstat\fR(2) system call when timestamps
beyond the range of 32-bit \fBtime_t\fR are encountered. In order to prevent
such spurious failures, \fBpcfs\fR by default clamps timestamps to the common
subset of possible \fBpcfs\fR timestamps and the range available to 32-bit
applications in Unix. The \fBclamptime\fR mount option therefore is active by
default. If you want access to the full range of possible timestamps on
\fBpcfs\fR, mount the file system with the \fBnoclamptime\fR mount option. Note
that if \fBnoclamptime\fR is used, only 64-bit applications will have access to
timestamps beyond January 19th 2038, 03:14:06 UTC; 32-bit applications will
encounter \fBEOVERFLOW\fR errors.
.RE

.sp
.ne 2
.na
\fB\fBfoldcase\fR | \fBnofoldcase\fR\fR
.ad
.sp .6
.RS 4n
Force uppercase characters in filenames to lowercase when reading them from the
filesystem. This is for compatibility with the previous behavior of \fBpcfs\fR.
The default is \fBnofoldcase\fR.
.RE

.sp
.ne 2
.na
\fB\fBhidden\fR | \fBnohidden\fR\fR
.ad
.sp .6
.RS 4n
Allow or disallow listing of files with hidden or system bits set. Option
\fBhidden\fR is the default. When \fBnohidden\fR is effect, hidden and system
files are neither visible nor accessible. Note that PCFS in previous releases
of the Solaris operating system used the \fBnohidden\fR option as the default.
.RE

.sp
.ne 2
.na
\fB\fBatime\fR | \fBnoatime\fR\fR
.ad
.sp .6
.RS 4n
Enable or disable write access timestamps on DOS-formatted media. Default for
fixed disks is \fBatime\fR, while for removable media \fBnoatime\fR is used.
The latter default is so that writes to flash-based media ("memory sticks") can
be minimized, to prolong lifetime.
.RE

.sp
.ne 2
.na
\fB\fBtimezone=\fItimezone\fR\fR\fR
.ad
.sp .6
.RS 4n
Timestamps on DOS-formatted media are recorded in the local time of the
recording system. This can cause confusion when accessing removable media in
which the recording and receiving system use different time zones. Use this
option to force media timestamps to be interpreted for a specific time zone.
The \fBmount_pcfs\fR command converts the given time zone name into a numerical
offset that is passed to the \fBpcfs\fR kernel module, using the same rules as
described in \fBenviron\fR(5) for the \fBTZ\fR environment variable. By
default, the \fBtimezone\fR value is taken from the \fBTZ\fR environment
variable.

.SH NOTES
.sp
.LP
If the directory on which a file system is to be mounted is a symbolic link,
the file system is mounted on the directory to which the symbolic link refers,
rather than on top of the symbolic link itself.
