Parameters

bf_id	The function to call, identified as an index to the builtin_function array.
apl	Contains the arguments to this function.
nr_args	The number of arguments the function takes.
ctptr	A constraint tree used in some (but not all) of the builtin functions.
result	Where to put the result of calling the function.

Returns

boolean: true on success, otherwise false.
