MONGOC_DATABASE_GET_COLLECTION_NAMES_WITH_OPTS(3)

NAME
mongoc_database_get_collection_names_with_opts - 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.

    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 database, 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 listCollections command.

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);
}
