+The
+.Fn Disk::total_size
+function provides the size of the specified disk.
+.Pp
+The
+.Fn Disk::free_space
+and
+.Fn Disk::contiguous_block
+functions provide the amount of total free space, and the largest contiguous
+block of free space, respectively.
+.Pp
+The
+.Fn Disk::sector_size
+function provides the disk's sector size.
+.Sh RETURN VALUES
+The
+.Fn Disk::total_size ,
+.Fn Disk::free_space ,
+and
+.Fn Disk::contiguous_block
+functions return the requested information in mebibytes (MiB).
+.Pp
+The
+.Fn Disk::sector_size
+function returns the sector size in bytes.
+.Sh EXAMPLES
+The following is a simple utility that prints the name, total size, and free
+space for each disk attached to the system:
