30 The \fBngettext\fP, \fBdngettext\fP and \fBdcngettext\fP functions attempt to
31 translate a text string into the user's native language, by looking up the
32 appropriate plural form of the translation in a message catalog.
34 Plural forms are grammatical variants depending on the a number. Some languages
35 have two forms, called singular and plural. Other languages have three forms,
36 called singular, dual and plural. There are also languages with four forms.
38 The \fBngettext\fP, \fBdngettext\fP and \fBdcngettext\fP functions work like
39 the \fBgettext\fP, \fBdgettext\fP and \fBdcgettext\fP functions, respectively.
40 Additionally, they choose the appropriate plural form, which depends on the
41 number \fIn\fP and the language of the message catalog where the translation
44 In the "C" locale, or if none of the used catalogs contain a translation for
45 \fImsgid\fP, the \fBngettext\fP, \fBdngettext\fP and \fBdcngettext\fP functions
46 return \fImsgid\fP if \fIn\fP == 1, or \fImsgid_plural\fP if \fIn\fP != 1.
48 If a translation was found in one of the specified catalogs, the appropriate
49 plural form is converted to the locale's codeset and returned. The resulting
50 string is statically allocated and must not be modified or freed. Otherwise
51 \fImsgid\fP or \fImsgid_plural\fP is returned, as described above.
53 \fBerrno\fP is not modified.
55 The return type ought to be \fBconst char *\fP, but is \fBchar *\fP to avoid
56 warnings in C code predating ANSI C.
