Function clockbound_now 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn clockbound_now(
    ctx: *mut clockbound_ctx,
    output: *mut clockbound_now_result,
) -> *const clockbound_err

Call to the now() operation of the ClockBound API.

Grab the most up to date data defining the clock error bound CEB, read the current time C(t) from the system clock and returns the interval [(C(t) - CEB), (C(t) + CEB)] in which true time exists. The call also populate an enum with the underlying clock status.

Safety

Have no choice but rely on the caller to pass valid pointers.
