A new TCP server is started on a user specified port using IPv4. Therefore a new socket is created and an address is bound to it.

Parameters

port	Port to listen on for incoming TCP connections.

Returns

On success, a file descriptor for the new socket is returned. On error, -1 is returned and errno ist set appropriately.

int tcp6_start_server

(

const char *

port

)

Start a new TCP server using IPv6.

A new TCP server is started on a user specified port using IPv6. Therefore a new socket is created and an address is bound to it.

Parameters

port	Port to listen on for incoming TCP connections.

Returns

On success, a file descriptor for the new socket is returned. On error, -1 is returned and errno ist set appropriately.
