gettxt - retrieve a text string
char *gettxt(const char *msgid, const char *dflt_str);
The gettxt() function retrieves a text string from a message
file. The arguments to the function are a message identifi-
cation msgid and a default string dflt_str to be used if the
The text strings are in files created by the mkmsgs utility
(see mkmsgs(1)) and installed in directories in
The directory locale can be viewed as the language in which
the text strings are written. The user can request that mes-
sages be displayed in a specific language 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 in
The user can also change the language in which the messages
are displayed by invoking the setlocale(3C) function with
the appropriate arguments.
If gettxt() fails to retrieve a message in a specific
language it will try to retrieve the same message in U.S.
English. On failure, the processing depends on what the
second argument dflt_str points to. A pointer to the second
argument is returned if the second argument is not the null
string. If dflt_str points to the null string, a pointer to
the U.S. English text string "Message not found!!\n" is
The following depicts the acceptable syntax of msgid for a
call to gettxt().
<msgid> = <msgfilename>:<msgnumber>
The first field is used to indicate the file that contains
the text strings and must be limited to 14 characters. These
characters must be selected from the set of all character
values excluding \0 (null) and the ASCII code for / (slash)
and : (colon). The names of message files must be the same
as the names of files created by mkmsgs and installed in
/usr/lib/locale/locale/LC_MESSAGES/*. The numeric field
indicates the sequence number of the string in the file. The
strings are numbered from 1 to n where n is the number of
strings in the file.
Upon failure to pass either the correct msgid or a valid
message number to gettxt(), a pointer to the text string
"Message not found!!\n" is returned.
It is recommended that gettext(3C) be used in place of this

UX is the name of the file that contains the messages and 10
is the message number.
