Creating sounds?

[Lizard]

Hey guys, yep it's me again.

It is my first time creating a map and my first time im working with scripting.
My second map of my cs is almost done.

All i need is an area that, when the player walks into it, starts the sound of a grunt and lets the sound run for about 10 seconds and then fades out again.


I've been looking around on the script site, i found two voids that might do the trick, but before doing anything i would like know from you guys if i have found the right voids.

The two i found was:

void FadeInSound(string& asSoundName, float afFadeTime, bool abPlayStart);


and

void StopSound(string& asSoundName, float afFadeTime);

I like to know if it are those two i have to use, and if it is how to set them up.
I would really appriciate your help
