4.4BSD-Lite Description
|
|||
|
|
.PP
|
|||
|
|
This cd-rom contains the source code,
|
|||
|
|
manual pages and other documentation,
|
|||
|
|
and research papers from the first revision of the University of California,
|
|||
|
|
Berkeley's 4.4BSD-Lite distribution.
|
|||
|
|
.PP
|
|||
|
|
The 4.4BSD-Lite software is copyrighted by the
|
|||
|
|
University of California and others,
|
|||
|
|
but may be freely redistributed and used in products without fee,
|
|||
|
|
as long as the due credit,
|
|||
|
|
copyright notice,
|
|||
|
|
and other requirements described in the file /COPYRIGHT are met.
|
|||
|
|
.PP
|
|||
|
|
The distribution includes both software developed at Berkeley and much
|
|||
|
|
software contributed by authors outside Berkeley.
|
|||
|
|
Please see the previous section of this document
|
|||
|
|
for a list of the many contributors to the system.
|
|||
|
|
.PP
|
|||
|
|
The layout of the 4.4BSD-Lite distribution is described
|
|||
|
|
in the \fIhier\fR(7) manual page, which follows.
|
|||
|
|
A table of contents and permuted index for the 4.4BSD-Lite manual pages
|
|||
|
|
follow as well.
|
|||
|
|
.PP
|
|||
|
|
The cd-rom is in ISO-9660 format,
|
|||
|
|
with Rock Ridge Extensions.
|
|||
|
|
For example, to mount on a 4.4BSD-Lite system
|
|||
|
|
on which the CD-ROM drive is connected as SCSI unit 1,
|
|||
|
|
ensure that the directory /cdrom exists,
|
|||
|
|
then enter ``mount -r -t cd9660 /dev/sd1a /cdrom''.
|
|||
|
|
To mount on a Sun,
|
|||
|
|
ensure that the directory /cdrom exists,
|
|||
|
|
then enter ``mount -r -t hsts /dev/sr0 /cdrom''.
|
|||
|
|
.PP
|
|||
|
|
The 4.4BSD-Lite distribution is a source distribution only,
|
|||
|
|
and does not contain program binaries for any architecture.
|
|||
|
|
It is not possible to compile or run this software without a
|
|||
|
|
pre-existing system that is already installed and running.
|
|||
|
|
In addition,
|
|||
|
|
the distribution does not include sources for the complete 4.4BSD system.
|
|||
|
|
It includes source code and manual pages for the C library,
|
|||
|
|
approximately 95% of the utilities distributed in 4.4BSD,
|
|||
|
|
and all but a few files from the kernel.
|
|||
|
|
The system is almost entirely ANSI C and IEEE POSIX 1003.1 and 1003.2
|
|||
|
|
standards compliant.

4.4BSD-Lite Features
|
|||
|
|
.PP
|
|||
|
|
The major new facilities available in the 4.4BSD-Lite release are
|
|||
|
|
a new virtual memory system,
|
|||
|
|
the addition of ISO/OSI networking support,
|
|||
|
|
a new virtual filesystem interface supporting filesystem stacking,
|
|||
|
|
a freely redistributable implementation of NFS,
|
|||
|
|
a log-structured filesystem,
|
|||
|
|
enhancement of the local filesystems to support
|
|||
|
|
files and filesystems that are up to $2 sup 63$ bytes in size,
|
|||
|
|
enhanced security and system management support,
|
|||
|
|
and the conversion to and addition of the IEEE Std1003.1 (``POSIX'')
|
|||
|
|
facilities and many of the IEEE Std1003.2 facilities.
|
|||
|
|
In addition, many new utilities and additions have been made to the C-library.
|
|||
|
|
The kernel sources have been reorganized to collect all machine-dependent
|
|||
|
|
files for each architecture under one directory,
|
|||
|
|
and most of the machine-independent code is now free of code
|
|||
|
|
conditional on specific machines.
|
|||
|
|
The user structure and process structure have been reorganized
|
|||
|
|
to eliminate the statically-mapped user structure and to make most
|
|||
|
|
of the process resources shareable by multiple processes.
|
|||
|
|
The system and include files have been converted to be compatible
|
|||
|
|
with ANSI C, including function prototypes for most of the exported
|
|||
|
|
functions.
|
|||
|
|
There are numerous other changes throughout the system.
|
|||
|
|
.NH 1
|

Changes in the Kernel
|
|||
|
|
.PP
|
|||
|
|
This release includes several important structural kernel changes.
|
|||
|
|
The kernel uses a new internal system call convention;
|
|||
|
|
the use of global (``u-dot'') variables for parameters and error returns
|
|||
|
|
has been eliminated,
|
|||
|
|
and interrupted system calls no longer abort using non-local goto's (longjmp's).
|
|||
|
|
A new sleep interface separates signal handling from scheduling priority,
|
|||
|
|
returning characteristic errors to abort or restart the current system call.
|
|||
|
|
This sleep call also passes a string describing the process state,
|
|||
|
|
which is used by the ps(1) program.
|
|||
|
|
The old sleep interface can be used only for non-interruptible sleeps.
|
|||
|
|
.PP
|
|||
|
|
Many data structures that were previously statically allocated
|
|||
|
|
are now allocated dynamically.
|
|||
|
|
These structures include mount entries, file entries,
|
|||
|
|
user open file descriptors, the process entries, the vnode table,
|
|||
|
|
the name cache, and the quota structures.
|
|||
|
|
.PP
|
|||
|
|
The 4.4BSD-Lite distribution adds support for several new
|
|||
|
|
architectures including
|
|||
|
|
SPARC-based Sparcstations 1 and 2,
|
|||
|
|
MIPS-based Decstation 3100 and 5000 and Sony NEWS,
|
|||
|
|
68000-based Hewlett-Packard 9000/300 and Omron Luna, and
|
|||
|
|
386-based Personal Computers.
|
|||
|
|
Both the HP300 and SPARC ports feature the ability to run binaries
|
|||
|
|
built for the native operating system (HP-UX or SunOS) by emulating
|
|||
|
|
their system calls.
|
|||
|
|
Though this native operating system compatibility was provided by the
|
|||
|
|
developers as needed for their purposes and is by no means complete,
|
|||
|
|
it is complete enough to run several non-trivial applications including
|
|||
|
|
those that require HP-UX or SunOS shared libraries.
|
|||
|
|
For example, the vendor supplied X11 server and windowing environment
|
|||
|
|
can be used on both the HP300 and SPARC.
|
|||
|
|

|
|
Virtual memory changes
|
|||
|
|
.PP
|
|||
|
|
The new virtual memory implementation is derived from the MACH
|
|||
|
|
operating system developed at Carnegie-Mellon,
|
|||
|
|
and was ported to the BSD kernel at the University of Utah.
|
|||
|
|
The MACH virtual memory system call interface has been replaced with the
|
|||
|
|
``mmap''-based interface described in the
|
|||
|
|
``Berkeley Software Architecture Manual (4.4 Edition)''
|
|||
|
|
(see the UNIX Programmer's Manual,
|
|||
|
|
Supplementary Documents, PSD:5).
|
|||
|
|
The interface is similar to the interfaces shipped
|
|||
|

Additions and changes to filesystems
|
|||
|
|
.PP
|
|||
|
|
The 4.4BSD-Lite distribution contains most of the interfaces
|
|||
|
|
specified in the IEEE Std1003.1 system interface standard.
|
|||
|
|
Filesystem additions include IEEE Std1003.1 FIFOs,
|
|||
|
|
byte-range file locking, and saved user and group identifiers.
|
|||
|
|
.PP
|
|||
|
|
A new virtual filesystem interface has been added to the
|
|||
|
|
kernel to support multiple filesystems.
|
|||
|
|
In comparison with other interfaces,
|
|||
|
|
the Berkeley interface has been structured for more efficient support
|
|||
|
|
of filesystems that maintain state (such as the local filesystem).
|
|||
|
|
The interface has been extended with support for stackable
|
|||
|
|
filesystems done at UCLA.
|
|||
|
|
These extensions allow for filesystems to be layered on top of each
|
|||
|
|
other and allow new vnode operations to be added without requiring
|
|||
|
|
changes to existing filesystem implementations.
|
|||
|
|
For example, the umap filesystem
|
|||
|
|
is used to mount a sub-tree of an existing filesystem
|
|||
|
|
that uses a different set of uids and gids than the local system.
|
|||
|
|
Such a filesystem could be mounted from a remote site via NFS or it
|
|||
|
|
could be a filesystem on removable media brought from some foreign
|
|||
|
|
location that uses a different password file.
|
|||
|
|
.PP
|
|||
|
|
In addition to the local ``fast filesystem,''
|
|||
|
|
we have added an implementation of the network filesystem (NFS)
|
|||
|
|
that fully interoperates with the NFS shipped by Sun and its licensees.
|
|||
|
|
Because our NFS implementation was implemented using only the
|
|||
|
|
publicly available NFS specification,
|
|||
|
|
it does not require a license from Sun to use in source or binary form.
|
|||
|
|
By default it runs over UDP to be compatible with Sun's implementation.
|
|||
|
|
However, it can be configured on a per-mount basis to run over TCP.
|
|||
|
|
Using TCP allows it to be used quickly and efficiently through
|
|||
|
|
gateways and over long-haul networks.
|
|||
|
|
Using an extended protocol, it supports Leases to allow a limited
|
|||
|
|
callback mechanism that greatly reduces the network traffic necessary
|
|||
|
|
to maintain cache consistency between the server and its clients.
|
|||
|
|
.PP
|
|||
|
|
A new log-structured filesystem has been added that provides
|
|||
|
|
near disk-speed output and fast crash recovery.
|
|||
|
|
It is still experimental in the 4.4BSD-Lite release,
|
|||
|
|
so we do not recommend it for production use.
|
|||
|
|
We have also added a memory-based filesystem that runs in
|
|||
|
|
pageable memory, allowing large temporary filesystems without
|
|||
|
|
requiring dedicated physical memory.
|
|||
|
|
.PP
|
|||
|
|
The local ``fast filesystem'' has been enhanced to do
|
|||
|
|
clustering which allows large pieces of files to be
|
|||
|
|
allocated contiguously resulting in near doubling
|
|||
|
|
of filesystem throughput.
|
|||
|
|
The filesystem interface has been extended to allow
|
|||
|
|
files and filesystems to grow to $2 sup 63$ bytes in size.
|
|||
|
|
The quota system has been rewritten to support both
|
|||
|
|
user and group quotas (simultaneously if desired).
|
|||
|
|
Quota expiration is based on time rather than
|
|||
|
|
the previous metric of number of logins over quota.
|
|||
|
|
This change makes quotas more useful on fileservers
|
|||
|
|
onto which users seldom log in.
|
|||
|
|
.PP
|
|||
|
|
The system security has been greatly enhanced by the
|
|||
|
|
addition of additional file flags that permit a file to be
|
|||
|
|
marked as immutable or append only.
|
|||
|
|
Once set, these flags can only be cleared by the super-user
|
|||
|
|
when the system is running single user.
|
|||
|
|
To protect against indiscriminate reading or writing of kernel
|
|||
|
|
memory, all writing and most reading of kernel data structures
|
|||
|
|
must be done using a new ``sysctl'' interface.
|
|||
|
|
The information to be accessed is described through an extensible
|
|||
|
|
``Management Information Base'' (MIB).

POSIX terminal driver changes
|
|||
|
|
.PP
|
|||
|
|
The biggest area of change is a new terminal driver.
|
|||
|
|
The terminal driver is similar to the System V terminal driver
|
|||
|
|
with the addition of the necessary extensions to get the
|
|||
|
|
functionality previously available in the 4.3BSD terminal driver.
|
|||
|
|
4.4BSD-Lite also adds the IEEE Std1003.1 job control interface,
|
|||
|
|
which is similar to the 4.3BSD job control interface,
|
|||
|
|
but adds a security model that was missing in the
|
|||
|
|
4.3BSD job control implementation.
|
|||
|
|
A new system call, \fIsetsid\fP,
|
|||
|
|
creates a job-control session consisting of a single process
|
|||
|
|
group with one member, the caller, that becomes a session leader.
|
|||
|
|
Only a session leader may acquire a controlling terminal.
|
|||
|
|
This is done explicitly via a \s-1TIOCSCTTY\s+1 \fIioctl\fP call,
|
|||
|
|
not implicitly by an \fIopen\fP call.
|
|||
|
|
The call fails if the terminal is in use.
|
|||
|
|
.PP
|
|||
|
|
For backward compatibility,
|
|||
|
|
both the old \fIioctl\fP
|
|||
|
|
calls and old options to \fIstty\fP
|
|||
|
|
are emulated.

Changes to the utilities
|
|||
|
|
.PP
|
|||
|
|
There are several new tools and utilities included in this release.
|
|||
|
|
A new version of ``make'' allows much-simplified makefiles for the
|
|||
|
|
system software and allows compilation for multiple architectures
|
|||
|
|
from the same source tree (which may be mounted read-only).
|
|||
|
|
Notable additions to the libraries include functions to traverse a
|
|||
|
|
filesystem hierarchy, database interfaces to btree and hashing functions,
|
|||
|
|
a new, fast implementation of stdio, and a radix sort function.
|
|||
|
|
The additions to the utility suite include greatly enhanced versions of
|
|||
|
|
programs that display system status information, implementations of
|
|||
|
|
various traditional tools described in the IEEE Std1003.2 standard,
|
|||
|
|
and many others.
|
|||
|
|
.PP
|
|||
|
|
We have been tracking the IEEE Std1003.2 shell and utility work
|
|||
|
|
and have included prototypes of many of the proposed utilities.
|
|||
|
|
Most of the traditional utilities have been replaced
|
|||
|
|
with implementations conformant to the POSIX standards.
|
|||
|
|
Almost the entire manual suite has been rewritten to
|
|||
|
|
reflect the POSIX defined interfaces.
|
|||
|
|
In rewriting this software, we have generally
|
|||
|
|
been rewarded with significant performance improvements.
|
|||
|
|
Most of the libraries and header files have been converted
|
|||
|
|
to be compliant with ANSI C.
|
|||
|
|
The system libraries and utilities all compile
|
|||
|
|
with either ANSI or traditional C.

.PP
|
|||
|
|
The Kerberos (version 4) authentication software has been
|

A new implementation of the \fIex/vi\fP text editors is available
|
|||
|
|
in this release.
|
|||
|
|
It is intended as a bug-for-bug compatible version of the editors.
|
|||
|
|
It also has a few new features: 8-bit clean data, lines and files
|
|||
|
|
limited only by memory and disk space, split screens, tags stacks
|
|||
|
|
and left-right scrolling among them.
|

|
|
.PP
|
|||
|
|
Nearly the entire C-library has been rewritten.
|
|||
|
|
Some highlights of the changes to the 4.4BSD-Lite C-library:
|
|||
|
|
.IP \(bu
|
|||
|
|
The newly added \fIfts\fP
|
|||
|
|
functions will do either physical or logical traversal of
|
|||
|
|
a file hierarchy as well as handle essentially infinite depth
|
|||
|
|
filesystems and filesystems with cycles.
|
|||
|
|
All the utilities in 4.4BSD-Lite that traverse file hierarchies
|
|||
|
|
have been converted to use \fIfts\fP.
|
|||
|
|
The conversion has always resulted in a significant performance
|
|||
|
|
gain, often of four or five to one in system time.
|
|||
|
|
.IP \(bu
|
|||
|
|
The newly added \fIdbopen\fP
|
|||
|
|
functions are intended to be a family of database access methods.
|
|||
|
|
Currently, they consist of \fIhash\fP,
|
|||
|
|
an extensible, dynamic hashing scheme,
|
|||
|
|
\fIbtree\fP, a sorted, balanced tree structure (B+tree's), and
|
|||
|
|
\fIrecno\fP, a flat-file interface for fixed or variable length records
|
|||
|
|
referenced by logical record number.
|
|||
|
|
Each of the access methods stores associated key/data pairs and
|
|||
|
|
uses the same record oriented interface for access.
|
|||
|
|
Future versions of this software may be retrieved by anonymous ftp
|
|||
|
|
from ftp.cs.berkeley.edu, in the directory ucb/4bsd.
|
|||
|
|
.IP \(bu
|
|||
|
|
The \fIqsort\fP
|
|||
|
|
function has been rewritten for additional performance.
|
|||
|
|
In addition, three new types of sorting functions,
|
|||
|
|
\fIheapsort\fP, \fImergesort\fP, and \fIradixsort\fP
|
|||
|
|
have been added to the system.
|
|||
|
|
The \fImergesort\fP
|
|||
|
|
function is optimized for data with pre-existing order,
|
|||
|
|
in which case it usually significantly outperforms \fIqsort\fP.
|
|||
|
|
The \fIradixsort\fP
|
|||
|
|
functions are variants of most-significant-byte radix sorting.
|
|||
|
|
They take time linear to the number of bytes to be
|
|||
|
|
sorted, usually significantly outperforming \fIqsort\fP
|
|||
|
|
on data that can be sorted in this fashion.
|
|||
|
|
An implementation of the POSIX 1003.2 standard \fIsort\fP
|
|||
|
|
based on \fIradixsort\fP is included in 4.4BSD-Lite.
|
|||
|
|
.IP \(bu
|
|||
|
|
The floating point support in the C-library has been replaced
|
|||
|
|
and is now accurate.
|
|||
|
|
.IP \(bu
|
|||
|
|
The C functions specified by both ANSI C, POSIX 1003.1 and
|
|||
|
|
1003.2 are now part of the C-library.
|
|||
|
|
This includes support for file name matching, shell globbing
|
|||
|
|
and both basic and extended regular expressions.
|
|||
|
|
.IP \(bu
|
|||
|
|
ANSI C multibyte and wide character support has been integrated.
|
|||
|
|
The rune functionality from the Bell Labs' Plan 9 system is provided
|
|||
|
|
as well.
|
|||
|
|
.IP \(bu
|
|||
|
|
The \fItermcap\fP
|
|||
|
|
functions have been generalized and replaced with a general
|
|||
|
|
purpose interface named \fIgetcap\fP.
|
|||
|
|
.IP \(bu
|
|||
|
|
The \fIstdio\fP
|
|||
|
|
routines have been replaced, and are usually much faster.
|
|||
|
|
In addition, the \fIfunopen\fP
|
|||
|
|
interface permits applications to provide their own I/O stream
|
|||
|
|
function support.

The manual pages give descriptions of the features of the
|
|||
|
|
4.4BSD system, as developed at the University of California at Berkeley.
|
|||
|
|
They do not attempt to provide perspective or tutorial information about the
|
|||
|
|
4.4BSD operating system, its facilities, or its implementation.
|
|||
|
|
Various documents on those topics are contained in the
|
|||
|
|
``\s-1UNIX\s+1 User's Supplementary Documents'' (USD), the
|
|||
|
|
``\s-1UNIX\s+1 Programmer's Supplementary Documents'' (PSD),
|
|||
|
|
and ``\s-1UNIX\s+1 System Manager's Manual'' (SMM).
|
|||
|
|
In particular, for an overview see ``The \s-1UNIX\s+1 Time-Sharing System'' (PSD:1)
|
|||
|
|
by Ritchie and Thompson; for a tutorial see
|
|||
|
|
``\s8\s-1UNIX\s+1\s10 for Beginners'' (USD:1) by Kernighan,
|
|||
|
|
and for an guide to the new features of this latest version, see
|
|||
|
|
``Berkeley Software Architecture Manual (4.4 Edition)'' (PSD:5).

Within the area it surveys, this volume attempts to be timely, complete
|
|||
|
|
and concise. Where the latter two objectives conflict,
|
|||
|
|
the obvious is often left unsaid in favor of brevity.
|
|||
|
|
It is intended that each program be described as it is, not as it should be.
|
|||
|
|
Inevitably, this means that various sections will soon be out of date.
|
|||
|

Commands are programs intended to be invoked directly by
|
|||
|
|
the user, in contrast to subroutines, that are
|
|||
|
|
intended to be called by the user's programs.
|
|||
|
|
User commands are described in URM section 1.
|
|||
|
|
Commands generally reside in directory
|
|||
|
|
.I /bin
|
|||
|
|
(for
|
|||
|
|
.IR bin \|ary
|
|||
|
|
programs).
|
|||
|
|
Some programs also reside in
|
|||
|
|
.I
|
|||
|
|
/\|usr/\|bin,
|
|||
|
|
.R
|
|||
|
|
to save space in
|
|||
|
|
.I /\|bin.
|
|||
|
|
.R
|
|||
|
|
These directories are searched automatically by the command interpreters.
|
|||
|
|
Additional directories that may be of interest include
|
|||
|
|
.I
|
|||
|
|
/\|usr/\|contrib/\|bin,
|
|||
|
|
.R
|
|||
|
|
which has contributed software
|
|||
|
|
.I
|
|||
|
|
/\|usr/\|old/\|bin,
|
|||
|
|
.R
|
|||
|
|
which has old but sometimes still useful software and
|
|||
|
|
.I
|
|||
|
|
/\|usr/\|local/\|bin,
|
|||
|
|
.R
|
|||
|
|
which contains software local to your site.

Games have been relegated to URM section 6 and
|
|||
|
|
.I
|
|||
|
|
/\|usr/\|games,
|
|||
|
|
.R
|
|||
|
|
to keep them from contaminating
|
|||
|
|
the more staid information of URM section 1.
|
|||
|
|
.LP
|
|||
|
|
Miscellaneous collection of information necessary for
|
|||
|
|
writing in various specialized languages such as character codes,
|
|||
|
|
macro packages for typesetting, etc is contained in URM section 7.
|

System calls are entries into the BSD kernel.
|
|||
|
|
The system call interface is identical to a C language
|
|||
|
|
procedure call; the equivalent C procedures are described in PRM section 2.
|
|||
|
|
.LP
|
|||
|
|
An assortment of subroutines is available;
|
|||
|
|
they are described in PRM section 3.
|
|||
|
|
The primary libraries in which they are kept are described in
|
|||
|
|
.IR intro (3).
|
|||
|
|
The functions are described in terms of C.
|
|||
|
|
.LP
|
|||
|
|
PRM section 4 discusses the characteristics of
|
|||
|
|
each system ``file'' that refers to an I/O device.
|
|||
|
|
The names in this section refer to the HP300 device names for the hardware,
|
|||
|
|
instead of the names of the special files themselves.
|
|||
|
|
.LP
|
|||
|
|
The file formats and conventions (PRM section 5)
|
|||
|
|
documents the structure of particular kinds of files;
|
|||
|
|
for example, the form of the output of the loader and
|
|||
|
|
assembler is given. Excluded are files used by only one command,
|
|||
|
|
for example the assembler's intermediate files.
|
|||
|
|
.LP
|
|||
|
|
Commands and procedures intended for use primarily by the
|
|||
|
|
system administrator are described in SMM section 8.
|
|||
|
|
The files described here are almost all kept in the directory
|
|||
|
|
.I /\|etc.
|
|||
|
|
The system administration binaries reside in
|
|||
|
|
.I
|
|||
|
|
/\|sbin,
|
|||
|
|
.R
|
|||
|
|
and
|
|||
|
|
.I
|
|||
|
|
/\|usr/\|sbin.

Each section consists of independent entries of a page or so each.
|
|||
|
|
The name of the entry is in the upper corners of its pages,
|
|||
|
|
together with the section number.
|
|||
|
|
Entries within each section are alphabetized.
|
|||
|
|
The page numbers of each entry start at 1;
|
|||
|
|
it is infeasible to number consecutively the pages of
|
|||
|
|
a document like this that is republished in many variant forms.
|
|||
|
|
.LP
|
|||

All entries are based on a common format;
|
|||
|
|
not all subsections always appear.

The

.IR synopsis ""

summarizes the use of the program being described.
|

A few conventions are used, particularly in the Commands subsection:
|

|
|
.LP
|
|||
|
|
.RS
|
|||
|
|
.B Boldface
|

|

words are considered literals, and are typed just as they appear.

Square brackets [ ] around an argument show that the argument is optional.
|
|||
|
|
When an argument is given as ``name'', it always refers to a file name.
|
|||
|
|
.LP
|
|||
|
|
Ellipses ``.\|.\|.'' are used to show that the previous argument-prototype
|
|||
|
|
may be repeated.
|
|||
|
|
.LP
|
|||
|
|
A final convention is used by the commands themselves.
|
|||
|
|
An argument beginning with a minus sign ``\-'' usually means that it is an
|
|||
|
|
option-specifying argument, even if it appears in a position where
|
|||
|
|
a file name could appear. Therefore, it is unwise to have files whose
|
|||
|
|
names begin with ``\-''.

At the beginning of URM, PRM, and SSM is a List of Manual Pages,
|
|||
|
|
organized by section and alphabetically within each section, and a
|
|||
|
|
Permuted Index derived from that List.
|
|||
|
|
Within each index entry, the title of the writeup to which
|
|||
|
|
it refers is followed by the appropriate section number in parentheses.
|
|||
|
|
This fact is important because there is considerable
|
|||
|
|
name duplication among the sections, arising principally from commands that
|
|||
|
|
exist only to exercise a particular system call.
|
|||
|
|
Finally, there is a list of documents on the inside back cover of each volume.
