Binds a TCP socket to specific port and accepts a connection. Listens to a TCP socket. The <port number> defines TCP port
Syntax
Accept( {#<Listening Device number>} , #<Accepting device number>, <port number>)
Type
<Listening device number> : Long
<Accepting device number> : Long
<Port number> : Long
Range
< Listening device number> : 1 to 255
< Accepting device number> : 1 to 255
<Port number> : 6000 through 6999
Scope
Task
Limitations
Task only
Errors:
- Invalid socket
- Cannot accept connection
Examples
EXAMPLE
Accept(#1,65456)
EXAMPLE - Versions 4.0.14 and higher:
Dim X as long = 2
OpenSocket Options=1 as #1 ‘explicit socket open for listening for port
while TRUE
OpenSocket Options=1 as #X ‘ explicit socket open for listening accepting a
‘ new connection
Accept(#1, #X, 6002)
X=X+1
End while
Where:
- ListeningDevice is permanent and bound to the port. It can be closed only when listener is terminated.
- AcceptingDevice[x] is created each time a listener creates new server task.
- Application cannot close AcceptingDevice[x] when it is accepting.
