Question On Emacs

[Antonis Matsakas]

Hi
I am a SW engineer starting using gnu emacs for the last 1 month. I have the
following question.
Can you have links in gnu emacs.
For example: the line where a function is called can link to the function
body regardless if it's in the same file or not?

i.e. Let's say can the following line (standard C code):
        if (dosomething() == True){
link to the function body:
Boolean dosomething()
{
function body
...
...
}
Am asking this because in this way I am able to visit large piece of code
(in the same or different modules
Thanks
