int addr_is_a_configured_bridge | ( | const tor_addr_t * | addr, |

const char * | digest | ||
) |
If we have a bridge configured whose digest matches digest, or a bridge with no known digest whose address matches addr:port, return 1. Else return 0. If digest is NULL, check for address/port matches only.

int extend_info_is_a_configured_bridge | ( | const extend_info_t * | ei | ) |
If we have a bridge configured whose digest matches ei->identity_digest, or a bridge with no known digest whose address matches ei->addr:ei->port, return 1. Else return 0. If ei->onion_key is NULL, check for address/port matches only.
Note that if the extend_info_t contains multiple addresses, we return true only if every address is a bridge.

void fetch_bridge_descriptors | ( | const or_options_t * | options, |

For each bridge in our list for which we don't currently have a descriptor, fetch a new copy of its descriptor – either directly from the bridge or via a bridge authority.
