Hello guys,
so how do we generate C header files automatically for a
library compiled with dmd, ldc
in betterC. Like basic example below. I found the "-HC" flag
which can be used to output C++ header files. Do I need to
convert those manually to C?
```D
export extern(C) {
uint add(uint a, uint b) {
return a + b;
}
}
```
dmd -c mycode.c -Hf=mycode.di
```
https://dlang.org/spec/importc.html#ctod
If you want to output the function bodies as D code, add
`-inline`:
```
dmd -c mycode.c -inline -Hf=mycode.di
```
