Warning:

Deprecated since version 1.9.0: Use mongoc_database_find_collections_with_opts() <> instead.



SYNOPSIS

mongoc_cursor_t *
mongoc_database_find_collections (mongoc_database_t *database,


                                  const bson_t *filter,


                                  bson_error_t *error);


DESCRIPTION

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.

PARAMETERS

  • 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

Errors are propagated via the error parameter.

RETURNS

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.
