# 1.33.0[−][src]Function core::arch::x86_64::_subborrow_u32

    pub unsafe fn _subborrow_u32(c_in: u8, a: u32, b: u32, out: &mut u32) -> u8

This is supported on x86-64 only.

Adds unsigned 32-bit integers `a` and `b` with unsigned 8-bit carry-in `c_in` (carry or overflow flag), and store the unsigned 32-bit result in `out`, and the carry-out is returned (carry or overflow flag).

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
