// also contains code that implements "exported" external functions.

//
|
|
// External functions in the interpreter are implemented by
|
|
// using the system's dynamic loader to look up the address of the function
|
|
// we want to invoke. If a function is found, then one of the
|
|
// many lle_* wrapper functions in this file will translate its arguments from
|
|
// GenericValues to the types the function is actually expecting, before the
|
|
// function is called.
