# x07-ffi-c

Use this skill when embedding an X07 program as a library.

## Canonical commands

- Emit C + header from a project manifest:
  - `x07 build --project x07.json --out target/out.c --emit-c-header target/out.h`

## Notes

- `--emit-c-header` disables emitting a `main` entrypoint, so the output is linkable/embeddable.
