Question

I need to know the simplest method to pass variable from custom module to its template
I have created the custom.module and placed custom.tpl.php in the module folder

function custom_menu(){
  $items = array();

  $items['custom'] = array(
    'title' => t('custom!'),
    'page callback' => 'custom_page',
    'access arguments' => array('access content'),
    'type' => MENU_CALLBACK,
  );

  return $items;
}

function custom_page() {

    $setVar = 'this is custom module';
    return theme('custom', $setVar);    
}

i have added theme function but it is not working, can any one suggest me what is wrong with this code

function theme_custom($arg) {
  return $arg['output'];
}

function custom_theme() {
  return array(
    'Bluemarine' => array(
        'variables' => 'output',
        'template' => 'Bluemarine',
     ),
  );
}

This works for me:

function custom_menu(){
  $items = array();

  $items['custom'] = array(
    'title' => t('custom!'),
    'page callback' => 'custom_page',
    'access arguments' => array('access content'),
    'type' => MENU_NORMAL_ITEM,
  );

  return $items;
}

function custom_page() {
    $result = db_query('SELECT * from node');
    return theme('custom', array('output' => $result));
}

function custom_theme() {
  return array(
    'custom' => array(
      'arguments' => array('output' => NULL),
      'template' => 'custom',
     ),
  );
}

function template_preprocess_custom(&$variables) {

}
