int tf6GetDefaultGatewayTunnel

(struct sockaddr_storage * endpointIpAddrPtr);

Function Description

This function only supports IPv6. This function gets the endpoint IP address of the default gateway tunnel into the user variable pointed to by endpointIpAddrPtr. If there is no default gateway tunnel configured, then this function returns TM_ENOENT.

Parameters

• endpointIpAddrPtr

  When this function returns TM_ENOERROR, then the memory that endpointIpAddrPtr points to is set to the tunnel endpoint IP address, which is the IPv4 address of the IPv6 router. The memory that this points to must be allocated by the caller, i.e. a local variable in the caller's address space.

Returns

• TM_ENOERROR

  Default gateway tunnel was found – IP address copied into endpointIpAddrPtr.

• TM_EINVAL

  endpointIpAddrPtr is NULL.

• TM_ENOENT

  Default gateway tunnel not found.
