        # Fiddle::Function.call

(from ruby core)
### Implementation from Function
---
    call(*args)

---

Calls the constructed Function, with `args`. Caller must ensure the
underlying function is called in a thread-safe manner if running in a
multi-threaded process.

Note that it is not thread-safe to use this method to directly or
indirectly call many Ruby C-extension APIs unless you don't pass
+need_gvl: true+ to Fiddle::Function#new.

For an example see Fiddle::Function
