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.

       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 <>.

       • opts: A bson_t <https://www.mongoc.org/libbson/current/bson_t.html> 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  <https://www
       .mongodb.com/docs/manual/reference/command/listCollections/>.

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()
       <https://www.mongoc.org/libbson/current/bson_strfreev.html>. 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);
          }
