11 char * bind_textdomain_codeset (const char * domainname,
12 const char * codeset);
13
15 The bind_textdomain_codeset function sets the output codeset for mes‐
16 sage catalogs for domain domainname.
17
18 A message domain is a set of translatable msgid messages. Usually, ev‐
19 ery software package has its own message domain.
20
21 By default, the gettext family of functions returns translated messages
22 in the locale's character encoding, which can be retrieved as nl_lang‐
23 info(CODESET). The need for calling bind_textdomain_codeset arises for
24 programs which store strings in a locale independent way (e.g. UTF-8)
25 and want to avoid an extra character set conversion on the returned
26 translated messages.
27
28 domainname must be a non-empty string.
29
30 If codeset is not NULL, it must be a valid encoding name which can be
31 used for the iconv_open function. The bind_textdomain_codeset function
32 sets the output codeset for message catalogs belonging to domain do‐
33 mainname to codeset. The function makes copies of the argument strings
34 as needed.
35
36 If codeset is NULL, the function returns the previously set codeset for
37 domain domainname. The default is NULL, denoting the locale's character
38 encoding.
39
41 If successful, the bind_textdomain_codeset function returns the current
42 codeset for domain domainname, after possibly changing it. The result‐
43 ing string is valid until the next bind_textdomain_codeset call for the
44 same domainname and must not be modified or freed. If a memory alloca‐
45 tion failure occurs, it sets errno to ENOMEM and returns NULL. If no
46 codeset has been set for domain domainname, it returns NULL.
47
49 The following error can occur, among others:
50
51 ENOMEM Not enough memory available.
52
54 The return type ought to be const char *, but is char * to avoid warn‐
55 ings in C code predating ANSI C.
