Each filesystem is described on a separate line; fields on each line are separated by tabs or spaces. The order of records in *fstab* is important because diskarbitrationd(8) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/diskarbitrationd.8.html#//apple_ref/doc/man/8/diskarbitrationd>, fsck(8) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/fsck.8.html#//apple_ref/doc/man/8/fsck>, mount(8) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/mount.8.html#//apple_ref/doc/man/8/mount>, and umount(8) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/umount.8.html#//apple_ref/doc/man/8/umount> sequen-sequentially tially iterate through *fstab* doing their thing. The first field, (_fs_*_*_spec_), describes the block special device, the local filesystem, or the remote filesystem to be mounted. The diskarbitrationd program supports the identification of a local filesystem uniquely by its UUID or by its volume name, irrespective of hardware configuration and of hardware parallelism, using the constructs ``UUID'' and ``LABEL''. The second field, (_fs_*_*_file_), describes the mount point for the filesys-filesystem. tem. For swap partitions, this field should be specified as ``none''. The third field, (_fs_*_*_vfstype_), describes the type of the filesystem. The system currently supports these types of filesystems: _ufs_ a local UNIX filesystem _nfs_ a Sun Microsystems compatible ``Network File System'' _swap_ a disk partition to be used for swapping _msdos_ a DOS compatible filesystem _cd9660_ a CD-ROM filesystem (as per ISO 9660) _procfs_ a file system for accessing process data _kernfs_ a file system for accessing kernel parameters _fdesc_ an implementation of /dev/fd _union_ a translucent filesystem The fourth field, (_fs_*_*_mntops_), describes the mount options associated with the filesystem. It is formatted as a comma separated list of options. It contains at least the type of mount (see _fs_*_*_type_ below) plus any additional options appropriate to the filesystem type. The option ``auto'' can be used in the ``noauto'' form to cause a file system not to be mounted automatically (with ``mount -a'', or system boot time). The type of the mount is extracted from the _fs_*_*_mntops_ field and stored separately in the _fs_*_*_type_ field (it is not deleted from the _fs_*_*_mntops_ field). If _fs_*_*_type_ is ``rw'' or ``ro'' then the filesystem whose name is given in the _fs_*_*_file_ field is normally mounted read-write or read-only on the specified special file. If _fs_*_*_type_ is ``sw'' then the special file is made available as a piece of swap space by the swapon(8) command at the end of the system reboot procedure. The fields other than _fs_*_*_spec_ and _fs_*_*_type_ are unused. If _fs_*_*_type_ is specified as ``xx'' the entry is ignored. This is useful to show disk partitions which are currently unused. The fifth field, (_fs_*_*_freq_), is used for these filesystems by the dump(8) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/dump.8.html#//apple_ref/doc/man/8/dump> command to determine which filesystems need to be dumped. If the fifth field is not present, a value of zero is returned and dump will assume that the filesystem does not need to be dumped. The sixth field, (_fs_*_*_passno_), is used by the fsck(8) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/fsck.8.html#//apple_ref/doc/man/8/fsck> program to determine the order in which filesystem checks are done at reboot time. The root filesystem should be specified with a _fs_*_*_passno_ of 1, and other filesys-filesystems tems should have a _fs_*_*_passno_ of 2. Filesystems within a drive will be checked sequentially, but filesystems on different drives will be checked at the same time to utilize parallelism available in the hardware. If the sixth field is not present or zero, a value of zero is returned and fsck will assume that the filesystem does not need to be checked. #define FSTAB_RW "rw" /* read-write device */ #define FSTAB_RO "ro" /* read-only device */ #define FSTAB_SW "sw" /* swap device */ #define FSTAB_XX "xx" /* ignore totally */ struct fstab { char *fs_spec; /* block special device name */ char *fs_file; /* filesystem path prefix */ char *fs_vfstype; /* type of filesystem */ char *fs_mntops; /* comma separated mount options */ char *fs_type; /* rw, ro, sw, or xx */ int fs_freq; /* dump frequency, in days */ int fs_passno; /* pass number on parallel fsck */ }; The proper way to read records from _fstab_ is to use the routines getfsent(3) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man3/getfsent.3.html#//apple_ref/doc/man/3/getfsent>, getfsspec(3) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man3/getfsspec.3.html#//apple_ref/doc/man/3/getfsspec>, getfstype(3) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man3/getfstype.3.html#//apple_ref/doc/man/3/getfstype>, and getfsfile(3) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man3/getfsfile.3.html#//apple_ref/doc/man/3/getfsfile>. *FILES* /etc/fstab The file *fstab* resides in _/etc_. *SEE* *ALSO* getfsent(3) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man3/getfsent.3.html#//apple_ref/doc/man/3/getfsent>, diskarbitrationd(8) <http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/diskarbitrationd.8.html#//apple_ref/doc/man/8/diskarbitrationd> *HISTORY* The *fstab* file format appeared in 4.0BSD. Darwin March 28, 2002 Darwin =--=-=-=-=-=-==--=-==- SVR4 Process informationMany versions of SVR4 provide a facility called `/proc' that can be used to examine the image of a running process using file-system subroutines. If GDB is configured for an operating system with this facility, the command |info proc| is available to report on several kinds of information about the process running your program. |info proc| works only on SVR4 systems that include the |procfs| code. This includes OSF/1 (Digital Unix), Solaris, Irix, and Unixware, but not HP-UX or GNU/Linux, for example.
|info proc|Summarize available information about the process. |info proc mappings|

-=-=-=-==--= Mac OS X implementsBeneath the appealing, easy-to-use interface of Mac OS X is a rock-solid foundation that is engineered for stability, reliability, and performance. This foundation is a core operating system commonly known as Darwin. Darwin integrates a number of technologies, most importantly Mach 3.0, operating-system services based on 4.4BSD (Berkeley Software Distribution), high-performance networking facilities, and support for multiple integrated file systems.
