Function xsCall

Call a Function.

xs.bindings.xsSlotRecord xsCall (
  scope xs.bindings.xsMachineRecord* the,
  const(xs.bindings.xsSlotRecord) this_,
  short id,
  const(xs.bindings.xsSlotRecord[]) params...
);

When a property or item of an instance is a reference to a function, you can call the function with the xsCall template. If the property or item is not defined by the instance or its prototypes or is not a reference to a function, xsCall throws an exception.
