[−][src]Function show_notes::e029::ffi::add
pub(super) unsafe extern "C" fn add(
a: c_int,
b: c_int
) -> c_int
A mostly-trivial example: addition in C instead of in Rust. (See
the docs for e029::add
for why it isn't totally trivial.)
You can use it in an unsafe
block like so:
ⓘThis example is not tested
unsafe { let result = add(1, 2); // 3, of course! }
