On Unix hosts, RETRO provides an optional set of words for using
|
||
|
|
network sockets.
|
||
|
|
<br/><br/>
|
||
|
|
<br/><br/>
|
||
|
|
To create a new socket, just run:
|
||
|
|
<br/><br/>
|
||
|
|
<tt class='indentedcode'>socket:create</tt>
|
||
|
|
<br/><br/>
|
||
|
|
This will return a socket handle.
|
||
|
|
<br/><br/>
|
||
|
|
<br/><br/>
|
||
|
|
To bind to a port, pass the port number and socket handle
|
||
|
|
to <span class="tt">socket:bind</span>. The port should be a string. This will return
|
||
|
|
0 if successful, -1 if not successful, and an error code.
|
||
|
|
<br/><br/>
|
||
|
|
<tt class='indentedcode'>'9998 @Sock socket:bind</tt>
|
||
|
|
<br/><br/>
|
||
|
|
<br/><br/>
|
||
|
|
To prepare a socket for incoming connections use socket:listen. This
|
||
|
|
will take a backlog count and a socket handle. It returns a flag
|
||
|
|
(0 success, -1 failed) and an error code.
|
||
|
|
<br/><br/>
|
||
|
|
<tt class='indentedcode'>#3 @Sock socket:listen</tt>
|
||
|
|
<br/><br/>
|
||
|
|
<br/><br/>
|
||
|
|
To accept connections pass the socket handle to <span class="tt">socket:accept</span>.
|
||
|
|
This returns a new socket for the connection and an error code.
|
||
|
|
<br/><br/>
|
||
|
|
<tt class='indentedcode'>@Sock socket:accept</tt>
|
||
|
|
<br/><br/>
|
||
|
|
<br/><br/>
|
||
|
|
To connect to a server using the socket:
|
||
|
|
<br/><br/>
|
||
|
|
<tt class='indentedcode'>'forth.works '70 socket:configure</tt>
|
||
|
|
<tt class='indentedcode'>@Sock socket:connect</tt>
|
||
|
|
<br/><br/>
|
||
|
|
<span class="tt">socket:connect</span> will return a status code and an error code.
|
||
|
|
<br/><br/>
|
||
|
|
<br/><br/>
|
||
|
|
To write a string to a socket, use <span class="tt">socket:send</span>. This will
|
||
|
|
take a string and a socket handle and will return the number
|
||
|
|
of bytes sent and an error code.
|
||
|
|
<br/><br/>
|
||
|
|
<tt class='indentedcode'>'test @Sock socket:send</tt>
|
||
|
|
<br/><br/>
|
||
|
|
<br/><br/>
|
||
|
|
To read data from a socket pass an address, a maximum number of
|
||
|
|
bytes, and the socket handle to <span class="tt">socket:recv</span>. This will return
|
||
|
|
the number of bytes received and an error code. The bytes will
|
||
|
|
be stored in memory starting at the specified address.
|
||
|
|
<br/><br/>
|
||
|
|
<tt class='indentedcode'>here #1024 @Sock socket:recv</tt>
|
||
|
|
<br/><br/>
|
||
|
|
<br/><br/>
|
||
|
|
To close a socket, pass the socket handle to <span class="tt">socket:close</span>.
|
||
|
|
<br/><br/>
|
||
|
|
<tt class='indentedcode'>@Socket socket:close</tt>
|
||
|
