Mouse function outputs?

Hello everybody, i was just wondering if it is possible to make a program where if a certain condition is true, it would output mouse functions?
For example:

Code:

---

x=1
if(x=1){
move mouse here and click
}

---

Im looking for something like that, just dont know what to do on the inside.
If somebody could point me to a library with functions like this, that would be extremely greatful.

This is going to be platform dependent, and also you should have.

Code:

---

if (x == 1)

---

As Methodz says, it would depend on which OS you are using.

Itll be on xp, i can get it on ubuntu eee. Would it be able to work with those? If not, i could do vista, but i hate vista, so that would be last resort

And can you perhaps describe in a bit more detail what you actually want to achieve? Simulate clicks in YOUR application, or in someone else application?
