help with admin_notices on save_post

Will not render the admin_notice… could someone kindly tell me how I can display the message “Ran Function A” after getting the return message from FuntionA?
Been wracking my head about this and I just can’t seem to get it done.

add_action('save_post', 'functionx');

functionx () {
  functionA; //returns 0 or 1
   //print_r === will print 0 or 1 (I can get info back.)
    if 1
    add_action('admin_notices' , create_function( '', "echo 'Ran Function A';" ) );
    else
    add_action('admin_notices' , create_function( '', "echo 'Cound not do this';" ) );
}
