◆ allowlist_socket_accept()

int Xcom_network_provider_library::allowlist_socket_accept ( int  fd,
site_def const *  xcom_config 
)
static

◆ announce_tcp()

result Xcom_network_provider_library::announce_tcp ( xcom_port  port)

◆ checked_create_socket()

staticprivate

◆ create_server_socket_v4()

staticprivate

◆ does_node_have_v4_address()

struct addrinfo * Xcom_network_provider_library::does_node_have_v4_address ( struct addrinfo *  retrieved)
static

Retrieves a node IPv4 address, if it exists.

If a node is v4 reachable, means one of two:

  • The raw address is V4
  • a name was resolved to a V4/V6 address

If the later is the case, we are going to prefer the first v4 address in the list, since it is the common language between old and new version. If you want exclusive V6, please configure your DNS server to serve V6 names

Parameters
retrieveda previously retrieved struct addrinfo
Returns
struct addrinfo* An addrinfo of the first IPv4 address. Else it will return the entry parameter.
