Function ipsetcallback_ 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn ipsetcallback_(
    fproblem: *mut *mut c_void,
    inter_cb: FIntermediate_CB,
)

ipsetcallback_(FProblem, INTER_CB) — install a Fortran-side intermediate callback.

Safety

fproblem must be valid; inter_cb must be a valid Fortran callback for the lifetime of the problem.
