mongoc_socket_t * mongoc_socket_new (int domain, int type, int protocol) BSON_GNUC_WARN_UNUSED_RESULT;
domain: An int containing the address family such as AF_INET.
type: An int containing the socket type such as SOCK_STREAM.
protocol: A protocol subset, typically 0.
Creates a new
mongoc_socket_t structure. This calls
socket() underneath to create a network socket.
A new socket if successful, otherwise
NULL and errno is set. The result should be freed with mongoc_socket_destroy() when no longer in use.
