LIS_INT lis_solver_get_rhistory(LIS_SOLVER solver, LIS_VECTOR v);
Get the residual history of the solver.

An error occurred
The vector v must be created in advance with the function lis_vector_create. When the vector v is shorter than the residual history, it stores the residual history in order to the vector v.
