Modules functions.php

Hi All,

I have one question that can we use function in tpl file which is define in modules/functions.php ?
If yes then how can we use it…?

If it can not be used in tpl file then how can we define common function for all tpl files…?

Please reply if anyone knows it.

Extend oxviewconfig then access it in tpl via $oViewConf

thanks its working…
