Does @see can be use to reference function by name?

Question

I know that it can point to a method, but if I want to reference a function from other file?

E.g:

/**
 * @see fn_name()
 */

is ok?

and can I use this tag inside other function?

Answer 1

As stated in documentation:

The @see tag can be used to define a reference to other Structural Elements or to an URI.

so yes, you can use @see to make reference to other method.
