ec_node_many()

struct ec_node * ec_node_many	(	const char *	id,
		struct ec_node *	child,
		unsigned int	min,
		unsigned int	max )

Create a many node that matches its child multiple times.

Parameters

id	The node identifier.
child	The child node. It is consumed and will be freed when the parent is freed, or immediately on error.
min	Minimum number of repetitions. Use 0 for no minimum.
max	Maximum number of repetitions. Use 0 for no maximum.

Returns

The node, or NULL on error (errno is set).

Examples

readline/main.c.

ec_node_many_set_params()

int ec_node_many_set_params	(	struct ec_node *	gen_node,
		struct ec_node *	child,
		unsigned int	min,
		unsigned int	max )

Set the parameters of a many node.

Parameters

gen_node	The many node.
child	The child node. It is consumed and will be freed when the parent is freed, or immediately on error.
min	Minimum number of repetitions. Use 0 for no minimum.
max	Maximum number of repetitions. Use 0 for no maximum.

Returns

0 on success, -1 on error (errno is set).
