This function serves the same purpose as the ECLiPSe built-in external/2:
- 
int ec_external(dident pred, int(*fct)(), dident module)
-  
 Creates a predicate pred in the given module, whose C/C++
	implementation is the function fct (see chapter 4
	for how to write such functions). The module must exist.
	Return code is PSUCCEED or an error code.
