<h2>DESCRIPTION</h2>

<p>The <b>bindtextdomain</b> function sets the base
directory of the hierarchy containing message catalogs for a
given message domain.</p>
<!-- INDENTATION -->
<p>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>
<!-- INDENTATION -->
<p>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>
<!-- INDENTATION -->
<p><i>domainname</i> must be a non-empty string.</p>
<!-- INDENTATION -->
<p>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>
<!-- INDENTATION -->
<p>If <i>dirname</i> is NULL, the function returns the
previously set base directory for domain
<i>domainname</i>.</p>

<p>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>
