This is useful for some applications, like writing lines onto an existing file. Since the user might change accidentally the context of the original file, great care should taken when handling a file with this routine. <p> <a href='im_open.3.html'>im_open(3)</a> is generally more convenient. <h2><a name='sect3' href='#toc3'>Return Value</a></h2> The function returns the image descriptor on success and NULL on error. <h2><a name='sect4' href='#toc4'>See Also</a></h2> <a href='im_close.3.html'>im_close(3)</a> , <a href='im_open.3.html'>im_open(3)</a> , <a href='im_makerw.3.html'>im_makerw(3)</a> . <h2><a name='sect5' href='#toc5'>Copyright</a></h2> <br> N.
