How to use the function ccbGetCollisionPointOfWorldWithLine(startX, startY, startZ, endX, endY, endZ) and to check if there is collision or not. The manual says it will return null. I don't understand this.

It will return an object (not null) if it finds a collision. The object is the point where the collision is. If it returns no object (=null), then no collision was found.
You can use it like this:
var collisionPoint = ccbGetCollisionPointOfWorldWithLine(...);
if (collisionPoint != null)
{
// this code inside here only gets run if there was a collision
}
