It returns <B>0 </B> if successful, <B>-1 </B> otherwise. The exception list files must be opened before <B>morphstr() </B> or <B>morphword()</B> are called. <P> <B>re_morphinit()</B> is used to close the exception list files and reopen them, and is used exclusively for WordNet development. Return codes are as described above. <P> <B>morphstr()</B> is the basic user interface to Morphy. It tries to find the base form (lemma) of the word or collocation <I>origstr </I> in the specified <I>pos </I>. The first call (with <I>origstr </I> specified) returns a pointer to the first base form found. Subsequent calls requesting base forms of the same string must be made with the first argument of <FONT SIZE=-1><B>NULL. </B></FONT> When no more base forms for <I>origstr </I> can be found, <FONT SIZE=-1><B>NULL </B></FONT> is returned. Note that <B>morphstr() </B> returns a pointer to a static character buffer. A subsequent call to <B>morphstr() </B> with a new string (instead of <B>NULL </B>) will overwrite the string pointed to by a previous call. Users should copy the returned string into a local buffer, or use the C library function <B>strdup </B> to duplicate the returned string into a <I>malloc'd </I> buffer. <P> <B>morphword()</B> tries to find the base form of <I>word </I> in the specified <I>pos </I>. This function is called by <B>morphstr()</B> for each individual word in a collocation. Note that <B>morphword() </B> returns a pointer to a static character buffer. A subsequent call to <B>morphword() </B> will overwrite the string pointed to by a previous call. Users should copy the returned string into a local buffer, or use the C library function <B>strdup </B> to duplicate the returned string into a <I>malloc'd </I> buffer. <H2><A NAME="sect3" HREF="#toc3">NOTES </A></H2> <B>morphinit()</B> is called by <B>wninit() </B> and is not intended to be called directly by an application. Applications wishing to use WordNet and/or the morphological functions must call <B>wninit() </B> at the start of the program. See <B><A HREF="wnutil.3WN.html">wnutil</B>(3WN)</A> for more information. <P> <I>origstr </I> may be either a word or a collocation formed by joining individual words with underscore characters (<B>_ </B>). <P> Usually only <B>morphstr() </B> is called from applications, as it works on both words and collocations. <P> <I>pos </I> must be one of the following: <P> <blockquote><B>1 </B><tt> </tt> <tt> </tt> NOUN <BR> <B>2 </B><tt> </tt> <tt> </tt> VERB <BR> <B>3 </B><tt> </tt> <tt> </tt> ADJECTIVE <BR> <B>4 </B><tt> </tt> <tt> </tt> ADVERB <BR> <B>5 </B><tt> </tt> <tt> </tt> ADJECTIVE_SATELLITE <BR> </blockquote> <P> If <FONT SIZE=-1><B>ADJECTIVE_SATELLITE </B></FONT> is passed, it is treated by <B>morphstr() </B> as <FONT SIZE=-1><B>ADJECTIVE. </B></FONT> <H2><A NAME="sect4" HREF="#toc4">SEE ALSO </A></H2> <B><A HREF="wnintro.3WN.html">wnintro</B>(3WN)</A> , <B><A HREF="wnsearch.3WN.html">wnsearch</B>(3WN)</A> , <B><A HREF="wndb.5WN.html">wndb</B>(5WN)</A> , <B><A HREF="morphy.7WN.html">morphy</B>(7WN)</A> . <P> <H2><A NAME="sect5" HREF="#toc5">WARNINGS </A></H2> Passing an invalid part of speech will result in a core dump. <P> The WordNet database files must be open to use <B>morphstr() </B> or <B>morphword(). <P> </B> <H2><A NAME="sect6" HREF="#toc6">BUGS </A></H2> Morphy will allow non-words to be converted to words, if they follow one of the rules described above.
