MONGOC_CLIENT_FIND_DATABASES_WITH_OPTS(3) libmongoc MONGOC_CLIENT_FIND_DATABASES_WITH_OPTS(3)

NAME

mongoc_client_find_databases_with_opts - mongoc_client_find_databases_with_opts()

SYNOPSIS

mongoc_cursor_t *
mongoc_client_find_databases_with_opts (

mongoc_client_t *client, const bson_t *opts) BSON_GNUC_WARN_UNUSED_RESULT;


Fetches a cursor containing documents, each corresponding to a database on this MongoDB server.

This function is considered a retryable read operation. Upon a transient error (a network error, errors due to replica set failover, etc.) the operation is safely retried once. If retryreads is false in the URI (see mongoc_uri_t) the retry behavior does not apply.

PARAMETERS

  • client: A mongoc_client_t.
  • opts: A bson_t containing additional options.

opts may be NULL or a BSON document with additional command options:

  • sessionId: First, construct a mongoc_client_session_t with mongoc_client_start_session(). You can begin a transaction with mongoc_client_session_start_transaction(), optionally with a mongoc_transaction_opt_t that overrides the options inherited from client, and use mongoc_client_session_append() to add the session to opts. See the example code for mongoc_client_session_t.
  • serverId: To target a specific server, include an int32 "serverId" field. Obtain the id by calling mongoc_client_select_server(), then mongoc_server_description_id() on its return value.

For a list of all options, see the MongoDB Manual entry on the listDatabases command.

ERRORS

Use mongoc_cursor_error() on the returned cursor to check for errors.

RETURNS

A cursor where each result corresponds to the server's representation of a database.

The cursor functions mongoc_cursor_set_limit(), mongoc_cursor_set_batch_size(), and mongoc_cursor_set_max_await_time_ms() have no use on the returned cursor.
