<H2>DESCRIPTION</H2>
|
|
|
|
The <B>bind_textdomain_codeset</B> function sets the output codeset for message
|
|
catalogs for domain <I>domainname</I>.
|
|
<P>
|
|
|
|
A message domain is a set of translatable <I>msgid</I> messages. Usually,
|
|
every software package has its own message domain.
|
|
<P>
|
|
|
|
By default, the <B>gettext</B> family of functions returns translated messages
|
|
in the locale's character encoding, which can be retrieved as
|
|
<B>nl_langinfo(CODESET)</B>. The need for calling <B>bind_textdomain_codeset</B>
|
|
arises for programs which store strings in a locale independent way (e.g.
|
|
UTF-8) and want to avoid an extra character set conversion on the returned
|
|
translated messages.
|
|
<P>
|
|
|
|
<I>domainname</I> must be a non-empty string.
|
|
<P>
|
|
|
|
If <I>codeset</I> is not NULL, it must be a valid encoding name which can be
|
|
used for the <B>iconv_open</B> function. The <B>bind_textdomain_codeset</B>
|
|
function sets the output codeset for message catalogs belonging to domain
|
|
<I>domainname</I> to <I>codeset</I>. The function makes copies of the argument
|
|
strings as needed.
|
|
<P>
|
|
|
|
If <I>codeset</I> is NULL, the function returns the previously set codeset for
|
|
domain <I>domainname</I>. The default is NULL, denoting the locale's character
|
|
encoding.
|
|
<A NAME="lbAE"> </A>
|
|
<H2>RETURN VALUE</H2>
|
|
|
|
If successful, the <B>bind_textdomain_codeset</B> function returns the current
|
|
codeset for domain <I>domainname</I>, after possibly changing it. The resulting
|
|
string is valid until the next <B>bind_textdomain_codeset</B> call for the same
|
|
<I>domainname</I> and must not be modified or freed. If a memory allocation
|
|
failure occurs, it sets <B>errno</B> to <B>ENOMEM</B> and returns NULL. If no
|
|
codeset has been set for domain <I>domainname</I>, it returns NULL.
|
|

|
|
<H2>ERRORS</H2>
|
|
|
|
The following error can occur, among others:
|
|
<DL COMPACT>
|
|
<DT id="1"><B>ENOMEM</B>
|
|
|
|
<DD>
|
|
Not enough memory available.
|
|
</DL>

<A NAME="lbAG"> </A>
|
|
<H2>BUGS</H2>
|
|
|
|
The return type ought to be <B>const char *</B>, but is <B>char *</B> to avoid
|
|
warnings in C code predating ANSI C.
