The value is +the address of the end of the text section for the file. For some +systems, there is no indication of the end of a source file, and you +just need to figure it ended when you see an <code>N_SO</code> for a different +source file, or a symbol ending in <code>.o</code> (which at least some +linkers insert to mark the start of a new <code>.o</code> file). +</p> +<hr> +<div class="header"> +<p> +Next: <a href="Include-Files.html#Include-Files" accesskey="n" rel="next">Include Files</a>, Previous: <a href="Main-Program.html#Main-Program" accesskey="p" rel="previous">Main Program</a>, Up: <a href="Program-Structure.html#Program-Structure" accesskey="u" rel="up">Program Structure</a> [<a href="index.html#SEC_Contents" title="Table of contents" rel="contents">Contents</a>][<a href="Symbol-Types-Index.html#Symbol-Types-Index" title="Index" rel="index">Index</a>]</p> +</div> + + + +</body> +</html> |
