Sample

void add_text( uint64_t truxton, uint64_t parent_file )
{
   truxton_start_adding_files( truxton );

   uint64_t child = truxton_child_file_create( truxton );

   char id[40];

   truxton_file_get_id( parent_file, id, sizeof(id) );
   truxton_child_file_set_parent_id( child, id );
   truxton_child_file_set_type( child, Type_ASCII_Text );
   truxton_child_file_set_name( child, "Hi.txt" );

   uint64_t now = truxton_time_now();

   truxton_child_file_set_created( child, now );
   truxton_child_file_set_accessed( child, now );
   truxton_child_file_set_modified( child, now );

   truxton_child_file_set_origin( child, ORIGIN_GENERATED );

   truxton_child_file_begin_write( child );

   char * message = "Hello World\n";

   truxton_child_file_write( child, message, strlen(message) );

   truxton_child_file_end_write( child );

   if ( truxton_child_file_save( child ) == 0 )
   {
