       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior), or
       the interface may not be implemented on Linux.

       The <i>catgets</i>() function shall attempt to read message <i>msg_id</i>, in set
       <i>set_id</i>, from the message catalog identified by <i>catd</i>.  The <i>catd</i>
       argument is a message catalog descriptor returned from an earlier
       call to <i>catopen</i>().  The results are undefined if <i>catd</i> is not a value
       returned by <i>catopen</i>() for a message catalog still open in the
       process. The <i>s</i> argument points to a default message string which
       shall be returned by <i>catgets</i>() if it cannot retrieve the identified
       message.

       The <i>catgets</i>() function need not be thread-safe.
</pre>
<h2><a id="RETURN_VALUE" href="catgets.3p.html#RETURN_VALUE"></a>RETURN VALUE  &nbsp; &nbsp; &nbsp; &nbsp; <a href="catgets.3p.html#top_of_page"><span class="top-link">top</span></a></h2><pre>
       If the identified message is retrieved successfully, <i>catgets</i>() shall
       return a pointer to an internal buffer area containing the null-
       terminated message string. If the call is unsuccessful for any
       reason, <i>s</i> shall be returned and <i><a href="errno.3.html">errno</a></i> shall be set to indicate the
       error.
</pre>
<h2><a id="ERRORS" href="catgets.3p.html#ERRORS"></a>ERRORS  &nbsp; &nbsp; &nbsp; &nbsp; <a href="catgets.3p.html#top_of_page"><span class="top-link">top</span></a></h2><pre>
       The <i>catgets</i>() function shall fail if:

       <b>EINTR  </b>The read operation was terminated due to the receipt of a
              signal, and no data was transferred.

       <b>ENOMSG </b>The message identified by <i>set_id</i> and <i>msg_id</i> is not in the
              message catalog.

       The <i>catgets</i>() function may fail if:

       <b>EBADF  </b>The <i>catd</i> argument is not a valid message catalog descriptor
              open for reading.

       <b>EBADMSG</b>
              The message identified by <i>set_id</i> and <i>msg_id</i> in the specified
              message catalog did not satisfy implementation-defined
              security criteria.

       <b>EINVAL </b>The message catalog identified by <i>catd</i> is corrupted.
