Define Documentation

#define get_flare_client_socket ( socket,
remoteip,
remoteport   ) 

Value:

socket = get_client_socket(remoteip,remoteport);\
        xsend(socket, &PEER_TYPE_FUSE, sizeof(peertype_t));
set socket to be a network socket initialized to talk flare protocol to server reached at IP address remoteip and IP port remoteport

Parameters:
socket resulting network socket
remoteip remote server IP address
remoteport remote server port

#define get_fuse_client_socket ( s,
ip,
port   )     get_flare_client_socket(s,ip,port)

an alias to get_flare_client_socket()

#define get_node_client_socket ( socket,
remoteip,
remoteport   ) 

Value:

socket = get_client_socket(remoteip,remoteport);\
        xsend(socket, &PEER_TYPE_NODE, sizeof(peertype_t));
set socket to be a network socket initialized to talk node protocol to server reached at IP address remoteip and IP port remoteport

Parameters:
socket resulting network socket
remoteip remote server IP address
remoteport remote server port

#define MAX_IP_LENGTH   16
