Common mistake.  Pointers to static arrays and pointer to pointers are
two different beasts.  What you need to do is create an intermediate
pointer:

char *pstring1;
pstring1 = string1;

And then when you pass it to the API you would pass &pstring1.  This is
because in C:

&string1 == &string1[0] == string1[];
&pstring1 != pstring1[0];
