strings parameters in C++ subroutine

[Don Fisher]

How does one convert a string parameter to a standard null terminated C
type string. I have been able to decode numeric values using 

value = (int) args(1).double_value();

type calls. But I do not know how to construct the same for character
strings. 

Is there documentation on how the arg lists and return value lists are
formatted?

thanks
don
