			The expression &b should be &b[0].  b is an array
			and is a pointer (sort of :-)).  You are passing
			a pointer to a pointer.  b[0] is the first element
			of b.  &b[0] points to it.

			I say 'sort of' because there are subtle differences
			between arrays and pointers in C.  Some people can
			explain the difference; others can explain trans-
			substantiation.  I shall attempt neither in a public
			forum.
