gettxt(3C)                       DG/UX 5.4.2                      gettxt(3C)


NAME
       gettxt - retrieve a text string

SYNOPSIS
       #include <nl_types.h>

       char *gettxt (const char *msgid, const char *dflt_str);

DESCRIPTION
       gettxt retrieves a text string from an AT&T-style message file. The
       arguments to the function are a message identification msgid and a
       default string dflt_str to be used if the retrieval fails.

       The text strings are in files created by the mkmsgs utility [see
       mkmsgs(1)] and installed in directories in
       /usr/lib/locale/locale/LC_MESSAGES.

       The directory locale can be viewed as the language in which the text
       strings are written.  The user can request that messages 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 /usr/lib/locale/C/LC_MESSAGES/*.

       The user can also change the language in which the messages are
       displayed by invoking the setlocale 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
       returned.

       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.

       On failure to pass the correct msgid or a valid message number to
       gettxt a pointer to the text string "Message not found!!\n" is
       returned.
