ipcreate_(N, X_L, X_U, M, G_L, G_U, NELE_JAC, NELE_HESS, IDX_STY, EVAL_F, EVAL_G, EVAL_GRAD_F, EVAL_JAC_G, EVAL_HESS) -> fptr

Returns an opaque handle (a Box) cast to a pointer; pass back to ipfree_ / ipsolve_.

Safety

All pointer arguments must be valid for the lifetime of the returned handle. Bound arrays must hold *N / *M doubles.
