Preface

HP-UX is the Hewlett-Packard Company’s implementation of a UNIX

operating system that is compatible with various industry standards. It

is based on the System V Release 4 operating system and includes

important features from the Fourth Berkeley Software Distribution.

The ten volumes of this manual contain the system reference

documentation, made up of individual entries called manpages, named

for the man command (see man (1)) that displays them on the system.

The entries are also known as manual pages or reference pages.

Typographical Conventions

audit (5) An HP-UX manpage reference. For example, audit is

the name and 5is the section in the HP-UX Reference.

On the web and on the Instant Information CD or

DVD, it may be a hyperlink to the manpage itself. From

the HP-UX command line, you can enter “man audit”

or “man 5 audit” to view the manpage. See man (1).

Book Title The title of a book. On the web and on the Instant

Information CD or DVD, it may be a hyperlink to the

book itself.

Command A command name or qualiﬁed command phrase.

ComputerOutput Text displayed by the computer.

Emphasis Text that is emphasized.

Emphasis Text that is strongly emphasized.

ENVIRONVAR The name of an environment variable.

[ERRORNAME] The name of an error number, usually returned in the

errno variable.

KeyCap The name of a (usually) nonprinting keyboard key, such

as Ctrl-X or Tab. Note that Return and Enter both refer to

the same key.

Replaceable

The name for a value that you replace in a command or

function, or information in a display that represents

several possible values.

Term The deﬁned use of an important word or phrase.

UserInput Commands and other text that you type.

Command Syntax

Literal A word or character that you enter literally.

Replaceable

A word or phrase that you replace with an appropriate

value.

chars

One or more grouped command options, such as -ikx.

The

chars

are usually a string of literal characters

that each represent a speciﬁc option. For example, the

entry -ikx is equivalent to the individual options -i,

-k, and -x. The plus character (+) is sometimes used as

an option preﬁx.

word

A single command option, such as -help. The

word

is a

literal keyword. The difference from -

chars

is usually

obvious and is clariﬁed in an Options description. The

plus character (+) and the double hyphen (--) are

sometimes used as option preﬁxes.

[ ] The bracket metacharacters enclose optional content in

formats and command descriptions.

{ } The brace metacharacters enclose required content in

formats and command descriptions.

| The bar metacharacter separates alternatives in a list

of choices, usually in brackets or braces.

... The ellipsis metacharacter after a token (

abc

...) or a

right bracket ([ ]...) or a right brace ({ }...)

metacharacter indicates that the preceding element

and its preceding whitespace, if any, may be repeated

an arbitrary number of times.

... Ellipsis is sometimes used to indicate omitted items in

a range.

Function Synopsis and Syntax

HP-UX functions are described in a deﬁnition format rather than a

usage format. The deﬁnition format includes type information that is

omitted when the function call is actually included in a program.

The function syntax elements are the same as for commands, except for

the options; see “Command Syntax” on page 7.

Function General

Deﬁnition

The general deﬁnition form is:

type func

(

type param

]... );

For example:

int setuname ( const char *

name

, size_t

namelen

);

Function Usage The usage form is:

func

(

param

]... );

For example:

setuname (

name

namelen

]... );

Publishing History

Revisions of the HP-UX Reference are published with each initial version

release and at signiﬁcant update milestones for each release. The

contents are current as of the publication dates. Since manpages are

often updated in software patches, you can ﬁnd the latest version of a

manpage on an appropriately patched system, using the man command.
