[Typo3] Properly link in ext

[Jernej Zorec]

Hi !

I have chosen a Field type: links in Ext Kickstarter for my extension.

Now I have problem making a href link out of it in my ext code.
If for link is chosen a file then the content
is something like: /fileadmin/blabla/bla.txt
If it is a webpage like www.google.com (it could also be like:
www.google.com _blank).

I'm 100% that there's a function that properly links this acording
of the link type. But what is it ? :)
