Always Show Your Work

Dear JC

I know how to solved the Pell's equations
x^2 - by^2 = 1
x^2 - by^2 = - 1
, but I am interested in the more general
x^2 - by^2 = c
Now I know if we have one solution
then we can find infinitely many solutions with
(p - q\sqrt {b})(r - s\sqrt {b})^n
is the first solution to
x^2 - by^2 = 1
My question is, how do we know when we have all the "primitive" solutions
that will generate all the solutions? (Also, is it possible that there would be infinite primitive solutions?)
