                                  const bson_t *filter,

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

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.

  • database: A mongoc_database_t.
  • filter: A matcher used by the server to filter the returned collections. May be NULL.
  • error: An optional location for a bson_error_t or NULL.

Errors are propagated via the error parameter.

This function returns a newly allocated mongoc_cursor_t that should be freed with mongoc_cursor_destroy() when no longer in use, or NULL in case of error. The user must call mongoc_cursor_next() on the returned mongoc_cursor_t to execute the initial command.

In the returned cursor each result corresponds to the server's representation of a collection in this 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.
