Typedefs

typedef void(* GNUNET_NAT_AddressCallback) (void *cls, void **app_ctx, int add_remove, enum GNUNET_NAT_AddressClass ac, const struct sockaddr *addr, socklen_t addrlen)
 Signature of the callback passed to GNUNET_NAT_register() for a function to call whenever our set of 'valid' addresses changes. More...
 
typedef void(* GNUNET_NAT_ReversalCallback) (void *cls, const struct sockaddr *remote_addr, socklen_t remote_addrlen)
 Signature of the callback passed to GNUNET_NAT_register(). More...
 
typedef void(* GNUNET_NAT_TestCallback) (void *cls, enum GNUNET_NAT_StatusCode result)
