           #include <libintl.h>
           char * gettext (const char * msgid);
           char * dgettext (const char * domainname, const char * msgid);
           char * dcgettext (const char * domainname, const char * msgid,
                             int category);


           The  gettext,  dgettext  and dcgettext functions attempt to translate a
           text string into the user's native language, by looking up the transla-
           tion in a message catalog.
           The  msgid argument identifies the message to be translated. By conven-
           tion, it is the English version of the message, with non-ASCII  charac-
           ters  replaced by ASCII approximations. This choice allows the transla-
           tors to work with message catalogs, called PO files, that contain  both
           the  English  and  the  translated versions of each message, and can be
           installed using the msgfmt utility.
           A message domain is a set  of  translatable  msgid  messages.  Usually,
           every  software  package has its own message domain. The domain name is
           used to determine the message catalog where the translation  is  looked
           up;  it  must  be  a  non-empty string. For the gettext function, it is
           specified through a preceding textdomain call.  For  the  dgettext  and
           dcgettext  functions,  it is passed as the domainname argument; if this
           argument is NULL, the domain name specified through a preceding textdo-
           main call is used instead.
           Translation  lookup  operates in the context of the current locale. For
           the gettext and dgettext functions, the  LC_MESSAGES  locale  facet  is
           used.  It  is determined by a preceding call to the setlocale function.
           setlocale(LC_ALL,"") initializes the LC_MESSAGES locale  based  on  the
           first nonempty value of the three environment variables LC_ALL, LC_MES-
           SAGES, LANG; see setlocale(3). For the dcgettext function,  the  locale
           facet  is  determined  by the category argument, which should be one of
           the LC_xxx  constants  defined  in  the  <locale.h>  header,  excluding
           LC_ALL. In both cases, the functions also use the LC_CTYPE locale facet
           in order to convert the translated message from the translator's  code-
           set  to the current locale's codeset, unless overridden by a prior call
           to the bind_textdomain_codeset function.
           The  message  catalog  used  by  the  functions  is  at  the   pathname
           dirname/locale/category/  Here  dirname  is the directory
           specified through bindtextdomain. Its default is system and  configura-
           tion  dependent;  typically  it is prefix/share/locale, where prefix is
           the installation prefix of the package. locale is the name of the  cur-
           rent  locale  facet; the GNU implementation also tries generalizations,
           such as the language name  without  the  territory  name.  category  is
           LC_MESSAGES  for  the  gettext  and dgettext functions, or the argument
           passed to the dcgettext function.
           is returned.


           errno is not modified.


           The  return type ought to be const char *, but is char * to avoid warn-
           ings in C code predating ANSI C.
           When an empty string is used for msgid,  the  functions  may  return  a
           nonempty string.
