cfd_solver_get_last_error Function

public function cfd_solver_get_last_error(handle, buffer, buffer_len) result(status) bind(c, name='cfd_solver_get_last_error'))

Copy the last surfaced error string into a C buffer.

When handle cannot be resolved, the function falls back to the process-wide API error string so callers can still retrieve create/resolve failures.
