# mongoc_database_find_collections_with_opts()

## Synopsis

    mongoc_cursor_t *
    mongoc_database_find_collections_with_opts (mongoc_database_t *database,
                                                const bson_t *opts);

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

## Parameters

- `database`: A mongoc_database_t.
- `opts`: Optional `bson_t` which may contain a subdocument named “filter”, and may contain additional options.

## 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 collection in this database.

## Examples

    {
       bson_t opts = BSON_INITIALIZER;
       bson_t name_filter;
       const bson_t *doc;
       bson_iter_t iter;
       bson_error_t error;

       BSON_APPEND_DOCUMENT_BEGIN (&opts, "filter", &name_filter);
       /* find collections with names like "abbbbc" */
       BSON_APPEND_REGEX (&name_filter, "name", "ab+c", NULL);
       bson_append_document_end (&opts, &name_filter);

       cursor = mongoc_database_find_collections_with_opts (database, &opts);
       while (mongoc_cursor_next (cursor, &doc)) {
          bson_iter_init_find (&iter, doc, "name");
          printf ("found collection: %s\n", bson_iter_utf8 (&iter, NULL));
       }

       if (mongoc_cursor_error (cursor, &error))
          fprintf (stderr, "%s\n", error.msg);
       }

       mongoc_cursor_destroy (cursor);
       bson_destroy (&opts);
    }
