Function redox::intrinsics::u16_sub_with_overflow

pub unsafe extern "rust-intrinsic" fn u16_sub_with_overflow(x: u16, y: u16) -> (u16, bool)

Unstable (core_intrinsics)

: intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Performs checked u16 subtraction.
