    <p>I'm having some trouble getting pread() to work in a header file. Every time I compile the program, it tells me that I have an because of the statement <code>#define _XOPEN_SOURCE 500</code>. The error is:</p> <pre><code>In file included from networking.h:6, from networking.c:1: /usr/include/bsd/stdlib.h:47: error: expected ‘)’ before ‘*’ token make: *** [all] Error 1 </code></pre> <p>The headers in the header file is </p> <pre><code>#ifndef NETWORKING_H #define NETWORKING_H #define _XOPEN_SOURCE 500 #include&lt;bsd/stdlib.h&gt; #include&lt;netinet/in.h&gt; #include&lt;sys/errno.h&gt; #include&lt;sys/types.h&gt; #include&lt;sys/socket.h&gt; #include&lt;ctype.h&gt; #include&lt;fcntl.h&gt; #include&lt;limits.h&gt; #include&lt;netdb.h&gt; #include&lt;pwd.h&gt; #include&lt;stdlib.h&gt; #include&lt;stdio.h&gt; #include&lt;string.h&gt; #include&lt;unistd.h&gt; #include"html.h" </code></pre> <p>Thanks!</p> <pre><code>#ifndef LIBBSD_STDLIB_H #define LIBBSD_STDLIB_H #include &lt;sys/cdefs.h&gt; #include &lt;sys/stat.h&gt; #include &lt;stdint.h&gt; #include &lt;stdlib.h&gt; /* For compatibility with NetBSD, which defines humanize_number here. */ #include &lt;libutil.h&gt; /* FIXME: Temporary inclusions to avoid API breakage, will be removed soon. */ #include &lt;bsd/stdio.h&gt; #include &lt;bsd/unistd.h&gt; __BEGIN_DECLS u_int32_t arc4random(); void arc4random_stir(); void arc4random_addrandom(u_char *dat, int datlen); int dehumanize_number(const char *str, int64_t *size); char *getprogname (); void setprogname (char *); </code></pre>

    2. COWhat makes you think the error is with the `#define _XOPEN_SOURCE 500` line? That's line 4, the error is on line 47 (unless there are 43 lines before the ones you quoted).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
