CSet:RemoveFirst

The RemoveFirst method removes the member at the head of the list.

member = CSet:RemoveFirst()

member is a reference to the member that was removed.

On success, this method returns the removed member.

On failure, nil is returned.

Removing the list member decreases the list length by 1 member.

Suppose a CSet exists with name S and that it contains 10 values. The following script removes the value at the head of the list:

Printf("count=%d", S:Count())

-- result: count=10

S:RemoveFirst()

-- remove the first member

Printf("count=%d", S:Count())

-- result: count=9
