with more standard exec() functions, however, because (1) it returns

<h3>THTTPD</h3>
<ul>
<li>
<code>CONFIG_THTTPD_PORT</code>: THTTPD Server port number
</li>
<li>
<code>CONFIG_THTTPD_IPADDR</code>: Server IP address (no host name)
</li>
<li>
<code>CONFIG_THTTPD_SERVER_ADDRESS</code>: SERVER_ADDRESS: response
</li>
<li>
<code>CONFIG_THTTPD_SERVER_SOFTWARE</code>: SERVER_SOFTWARE: response
</li>
<li>
<code>CONFIG_THTTPD_CGI_PATH</code>:
</li>
<li>
<code>CONFIG_THTTPD_CGI_PATTERN</code>: Only CGI programs matching this
pattern will be executed. In fact, if this value is not defined
then no CGI logic will be built.
</li>
<li>
<code>CONFIG_THTTPD_CGI_PRIORITY</code>: Provides the priority of CGI child tasks
</li>
<li>
<code>CONFIG_THTTPD_CGI_STACKSIZE</code>: Provides the initial stack size of
CGI child task (will be overridden by the stack size in the NXFLAT
header)
</li>
<li>
<code>CONFIG_THTTPD_CGI_BYTECOUNT</code>: Byte output limit for CGI tasks.
</li>
<li>
<code>CONFIG_THTTPD_CGI_TIMELIMIT</code>: How many seconds to allow CGI programs
to run before killing them.
</li>
<li>
<code>CONFIG_THTTPD_CGI_OUTFD</code>: In NuttX, CGI cannot use stdout for output.
Rather, it must use this file descriptor number.
</li>
<li>
<code>CONFIG_THTTPD_CHARSET- The default character set name to use with
text MIME types.
</li>
<li>
<code>CONFIG_THTTPD_IOBUFFERSIZE</code>:
</li>
<li>
<code>CONFIG_THTTPD_INDEX_NAMES</code>: A list of index filenames to check. The
files are searched for in this order.
</li>
<li>
<code>CONFIG_AUTH_FILE</code>: The file to use for authentication. If this is
defined then thttpd checks for this file in the local directory
before every fetch. If the file exists then authentication is done,
otherwise the fetch proceeds as usual. If you leave this undefined
then thttpd will not implement authentication at all and will not
check for auth files, which saves a bit of CPU time. A typical
value is &quot;.htpasswd&quout;
</li>
<li>
<code>CONFIG_THTTPD_LISTEN_BACKLOG</code>: The listen() backlog queue length.
</li>
<li>
<code>CONFIG_THTTPD_LINGER_MSEC</code>: How many milliseconds to leave a connection
open while doing a lingering close.
</li>
<li>
<code>CONFIG_THTTPD_OCCASIONAL_MSEC</code>: How often to run the occasional
cleanup job.
</li>
<li>
<code>CONFIG_THTTPD_IDLE_READ_LIMIT_SEC</code>: How many seconds to allow for
reading the initial request on a new connection.
</li>
<li>
<code>CONFIG_THTTPD_IDLE_SEND_LIMIT_SEC</code>: How many seconds before an
idle connection gets closed.
</li>
<li>
<code>CONFIG_THTTPD_TILDE_MAP1 and CONFIG_THTTPD_TILDE_MAP2</code>: Tilde mapping.
Many URLs use ~username to indicate a user's home directory. thttpd
provides two options for mapping this construct to an actual filename.
<ol>
<li>
Map ~username to &lt;prefix&gt;/username. This is the recommended choice.
Each user gets a subdirectory in the main web tree, and the tilde
construct points there. The prefix could be something like "users",
or it could be empty.
</li>
<li>
Map ~username to &lt;user's homedir&gt;/&lt;postfix&gt;. The postfix would be
the name of a subdirectory off of the user's actual home dir,
something like &quot;public_html&quot;.
</li>
</ol>
You can also leave both options undefined, and thttpd will not do
anything special about tildes. Enabling both options is an error.
Typical values, if they're defined, are &quot;users&quot; for
CONFIG_THTTPD_TILDE_MAP1 and &quot;public_html&quot; forCONFIG_THTTPD_TILDE_MAP2.
</li>
<li>
<code>CONFIG_THTTPD_GENERATE_INDICES
</li>
<li>
<code>CONFIG_THTTPD_URLPATTERN</code>: If defined, then it will be used to match
and verify referrers.
</li>
