NAME


gettxt - retrieve a text string from a message database

SYNOPSIS


gettxt msgfile : msgnum [dflt_msg]


DESCRIPTION


gettxt retrieves a text string from a message file in the directory
/usr/lib/locale/locale/LC_MESSAGES . The directory name locale
corresponds to the language in which the text strings are written; see
setlocale(3C).

msgfile
Name of the file in the directory
/usr/lib/locale/locale/LC_MESSAGES to retrieve msgnum from.
The name of msgfile can be up to 14 characters in length,
but may not contain either \0 (null) or the ASCII code for /
(slash) or : (colon).


msgnum
Sequence number of the string to retrieve from msgfile. The
strings in msgfile are numbered sequentially from 1 to n,
where n is the number of strings in the file.


dflt_msg
Default string to be displayed if gettxt fails to retrieve
msgnum from msgfile. Nongraphic characters must be
represented as alphabetic escape sequences.


The text string to be retrieved is in the file msgfile, created by the
mkmsgs(1) utility and installed under the directory
/usr/lib/locale/locale/LC_MESSAGES . You control which directory is
searched by setting the environment variable LC_MESSAGES. If LC_MESSAGES
is not set, the environment variable LANG will be used. If LANG is not
set, the files containing the strings are under the directory
/usr/lib/locale/C/LC_MESSAGES .


If gettxt fails to retrieve a message in the requested language, it will
try to retrieve the same message from /usr/lib/locale/C/LC_MESSAGES/
msgfile. If this also fails, and if dflt_msg is present and non-null,
then it will display the value of dflt_msg; if dflt_msg is not present or
is null, then it will display the string Message not found!!.

EXAMPLES


Example 1: The environment variables LANG and LC_MESSAGES.




If the environment variables LANG or LC_MESSAGES have not been set to
other than their default values, the following example:


example% gettxt UX:10 "hello world\n"


will try to retrieve the 10th message from /usr/lib/locale/C/UX/msgfile.
If the retrieval fails, the message "hello world," followed by a newline,
will be displayed.


ENVIRONMENT VARIABLES


See environ(5) for descriptions of the following environment variables
that affect the execution of gettxt: LC_CTYPE and LC_MESSAGES.

LC_CTYPE
Determines how gettxt handles characters. When LC_CTYPE
is set to a valid value, gettxt can display and handle
text and filenames containing valid characters for that
locale. gettxt can display and handle Extended Unix Code
(EUC) characters where any individual character can be 1,
2, or 3 bytes wide. gettxt can also handle EUC characters
of 1, 2, or more column widths. In the "C" locale, only
characters from ISO 8859-1 are valid.


LC_MESSAGES
Determines how diagnostic and informative messages are
presented. This includes the language and style of the
messages, and the correct form of affirmative and
negative responses. In the "C" locale, the messages are
presented in the default form found in the program itself
(in most cases, U.S. English).
