<h2>NAME
<a name="NAME"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">bindtextdomain
− set directory containing message catalogs</p>
<h2>SYNOPSIS
<a name="SYNOPSIS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em"><b>#include
<libintl.h></b></p>
<p style="margin-left:11%; margin-top: 1em"><b>char *
bindtextdomain (const char *</b> <i>domainname</i><b>, const
char *</b> <i>dirname</i><b>);</b></p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The
<b>bindtextdomain</b> function sets the base directory of
the hierarchy containing message catalogs for a given
message domain.</p>
<p style="margin-left:11%; margin-top: 1em">A message
domain is a set of translatable <i>msgid</i> messages.
Usually, every software package has its own message domain.
The need for calling <b>bindtextdomain</b> arises because
packages are not always installed with the same prefix as
the <libintl.h> header and the libc/libintl
libraries.</p>
<p style="margin-left:11%; margin-top: 1em">Message
catalogs will be expected at the pathnames
<i>dirname</i>/<i>locale</i>/<i>category</i>/<i>domainname</i>.mo,
where <i>locale</i> is a locale name and <i>category</i> is
a locale facet such as <b>LC_MESSAGES</b>.</p>
<p style="margin-left:11%; margin-top: 1em"><i>domainname</i>
must be a non-empty string.</p>
<p style="margin-left:11%; margin-top: 1em">If
<i>dirname</i> is not NULL, the base directory for message
catalogs belonging to domain <i>domainname</i> is set to
<i>dirname</i>. The function makes copies of the argument
strings as needed. If the program wishes to call the
<b>chdir</b> function, it is important that <i>dirname</i>
be an absolute pathname; otherwise it cannot be guaranteed
that the message catalogs will be found.</p>
<p style="margin-left:11%; margin-top: 1em">If
<i>dirname</i> is NULL, the function returns the previously
set base directory for domain <i>domainname</i>.</p>
<h2>RETURN VALUE
<a name="RETURN VALUE"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">If successful,
the <b>bindtextdomain</b> function returns the current base
directory for domain <i>domainname</i>, after possibly
changing it. The resulting string is valid until the next
<b>bindtextdomain</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.</p>
<h2>ERRORS
<a name="ERRORS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The following
error can occur, among others:</p>
<table width="100%" border="0" rules="none" frame="void"
cellspacing="0" cellpadding="0">
<tr valign="top" align="left">
<td width="11%"></td>
<td width="9%">
<p><b>ENOMEM</b></p></td>
<td width="2%"></td>
<td width="43%">
<p>Not enough memory available.</p></td>
<td width="35%">
</td></tr>
</table>
<h2>BUGS
<a name="BUGS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The return type
ought to be <b>const char *</b>, but is <b>char *</b> to
avoid warnings in C code predating ANSI C.</p>
