# mongoc_database_get_collection_names_with_opts()

## Synopsis

    char **
    mongoc_database_get_collection_names_with_opts (mongoc_database_t *database,
                                                    const bson_t *opts,
                                                    bson_error_t *error);

Fetches a `NULL` terminated array of `NULL-byte` terminated `char*` strings containing the names of all of the collections in `database`.

## Parameters

- `database`: A mongoc_database_t.
- `opts`: A `bson_t` containing additional options.
- `error`: An optional location for a bson_error_t or `NULL`.

## Errors

Errors are propagated via the `error` parameter.

## Returns

A `NULL` terminated array of `NULL` terminated `char*` strings that should be freed with `bson_strfreev()`. Upon failure, `NULL` is returned and `error` is set.

## Examples

    {
       bson_t opts = BSON_INITIALIZER;
       mongoc_read_concern_t *rc;
       bson_error_t error;
       char **strv;
       unsigned i;

       rc = mongoc_read_concern_new ();
       mongoc_read_concern_set_level (rc, MONGOC_READ_CONCERN_LEVEL_MAJORITY);
       mongoc_read_concern_append (rc, &opts);
       if ((strv = mongoc_database_get_collection_names_with_opts (
              database, &opts, &error))) {

          for (i = 0; strv[i]; i++)
             printf ("%s\n", strv[i]);

          bson_strfreev (strv);
       } else {
          fprintf (stderr, "Command failed: %s\n", error.message);
       }

       mongoc_read_concern_destroy (rc);
       bson_destroy (&opts);
    }
