error: incorrect function inside `extern` block
|
|
--> $DIR/extern-ffi-fn-with-body.rs:2:8
|
|
|
|
|
LL | extern "C" {
|
|
| ---------- `extern` blocks define existing foreign functions and functions inside of them cannot have a body
|
|
LL | fn foo() -> i32 {
|
|
| ________^^^__________-
|
|
| | |
|
|
| | cannot have a body
|
|
LL | | return 0;
|
|
LL | | }
|
|
| |_____- help: remove the invalid body: `;`
|
|
|
|
|
= help: you might have meant to write a function accessible through FFI, which can be done by writing `extern fn` outside of the `extern` block
