<h2>Prototype</h2>
<pre>
#include "webs.h"
int <b>websOpen</b>(int port, int retries);

<h2>Description</h2>
<P>The websOpen procedure is the main initialization
procedure for the GoAhead WebServer. It creates all the URL handlers,
initializes the mime type table and finally calls
<A href="websOpenListen.htm">websOpenListen</A>to open the primary TCP/IP port on which
the GoAhead WebServer will listen. You should call
<A href="websClose.htm">websClose</A> when you wish to shutdown the GoAhead
WebServer.</P>
<P>
</P>
<P>The
<EM> port</EM>parameter
specifies the TCP/IP to open. If this cannot be opened and
<EM >
retries</EM>is greater than zero, the next port in sequence will be
opened for up to
<EM>
retries
</EM>times until a port is
successfully opened. To determine the port number actually opened, call
<A href="websGetPort.htm" >
websGetPort
</a>
.</P>
<h2>Return Value</h2>
<p>Returns 0 if the open succeeds, otherwise -1 is returned.</p>
<h2>Example</h2>
<pre>
if (websOpen() < 0) {
/* Can't initialize */
}
</pre>
