[wp-hackers] Accessing a plugins function from theme

Thanks for the replies. I see now that I probably should have clarified a
bit more :)

I have done this but my function isn't getting called like it should. I get
a "call to undefined function" error when I access the theme file.

I have declared a function foo() in my plugins base file. I haven't attached
it to any filters or hooks of any kind. In my theme file I call the function
simply by 

if ( function_exists ( 'foo' ) )

Have I missed anything, or should that "just work"?

Thanks again!

You may also wish to wrap that function in a function_exists() call to
ensure that the theme doesn't error out if the plugin is deactivated.
