		PN	sig,
		PN_SIZE	extra
	)

Definition at line 17 of file objmodel.c.

int potion_sig_arity	(	Potion *	P,
		PN	sig
	)

number of args of sig tuple, implements the potion_closure_arity method.

sigs are encoded as tuples of len 2-3, (name type|modifier [default-value]) names String, modifiers Num. types also Num, but want to switch to special SIG VTable. default-value can be a value of any type and is prefixed with ':'

Returns: number of args as integer

Definition at line 87 of file objmodel.c.
