## Calling V from C
Since V can compile to C, calling V code from C is very easy.
By default all V functions have the following naming scheme in C: `[module name]__[fn_name]`.
For example, `fn foo() {}` in module `bar` will result in `foo__bar()`.
To use a custom export name, use the `[export]` attribute:
```
[export: 'my_custom_c_name']
fn foo() {
}
```
