int tfTeldUserBind	(
	ttUserTeldSrvHandle userSrvHandle,
	const struct sockaddr_storage TM_FAR * sockAddrPtr
	);

Function Description

This function binds the specified server to a port and IP address. This function must be called prior to calling tfTeldUserExecuteHandle(). If you are using the Strong End System Model (configuration macro TM_USE_STRONG_ESL) to bind multiple servers to different interfaces, you should call tfTeldUserSetSockopt() with the SO_BINDTODEVICE option prior to calling tfTeldUserBind().

You can specify a NULL value for sockAddrPtr to use the default TELNET server binding (see the discussion below).

Parameters

• userSrvHandle

  The server handle, as returned by tfTeldUserCreate().

• sockAddrPtr

  The pointer to a socket address at which to accept connections. Include the address family (AF_INET or AF_INET6), IP address, port number, and structure length.

  Specify a NULL pointer to accept connections on the default Telnet port (23), any local IP address, any interface, and for any supported address family.

Returns

• TM_ENOERROR

  Success

• TM_EPERM

  Not initialized; call tfTeldUserInit() first, or
  Server is already running.

• TM_ESHUTDOWN

  Server is stopped.

• TM_EINVAL

  Invalid parameter.

• TM_EADDRINUSE

  The address is already in use.
