tcpip_servopen - aleslab/Psychtoolbox-3-aleslab-fork GitHub Wiki

TCPIP_SERVOPEN opens a blocking TCPIP server socket.

fid = tcpip_servopen(port)

port is the port number of the socket you wish to open.

fid is the retuned handle to the socket, if successful,
-1 if unsuccessful.

This function is obsolete. It has been replaced with TCPIP_SERVSOCKET
and TCPIP_LISTEN. It is only included for backward compatibility.

TCPIP_SERVOPEN opens a TCPIP server socket with the requested PORT
number. This function blocks (waits) until a client socket has
established a connection before returning FID.

disp('Waiting for someone to connect to port 4444...');  
fid = tcpip\_servopen(4444);  
if fid = -1  
  error('TCP/IP Connection error!');  
end  
disp('Connection! :-)');  
disp('Now sending a message and closing!')  
tcpip\_write('Hello!!',string(10)); %string(10) generates newline  
tcpip\_close(fid);
