# tests/ffi
|
|
|
|
## Requirements
|
|
|
|
gcc for library compiling (for external-\*)
|
|
|
|
## Test Results
|
|
|
|
**External tests**
|
|
|
|
- [x] [external_math](./external_math/init.luau)
|
|
- [x] [external_pointer](./external_pointer/init.luau)
|
|
- [x] [external_print](./external_print/init.luau)
|
|
- [x] [external_struct](./external_struct/init.luau)
|
|
- [x] [external_closure](./external_closure/init.luau)
|
|
|
|
**Luau-side**
|
|
|
|
- [ ] [pretty_print](./pretty_print)
|
|
|
|
> need box, ref test
|
|
|
|
- [x] [isInteger](./isInteger)
|
|
- [ ] [into_boundary](./into_boundary)
|
|
|
|
> need assertion
|
|
|
|
- [ ] [from_boundary](./from_boundary)
|
|
|
|
> need assertion
|
|
|
|
- [ ] [cast](./cast)
|
|
|
|
> need assertion
|
|
|
|
## Benchmark Results
|
|
|
|
> Note: LuaJit's os.clock function returns process CPU time (used) which much smaller then Luau's os.clock output. In this benchmark, luau uses 'time.h' instead of os.clock. See [utility/proc_clock](./utility/proc_clock/init.luau)

|
**Target external c function**
|
|
|
|
```c
|
|
int add(int a, int b) {
|
|
return a + b;
|
|
}
|
|
```
