Function Documentation

ec_node_int()

struct ec_node * ec_node_int	(	const char *	id,
		int64_t	min,
		int64_t	max,
		unsigned int	base )

Create a signed integer node.

Parameters

id	The node identifier.
min	The minimum valid value (included).
max	The maximum valid value (included).
base	The base to use for parsing. If 0, try to guess from prefix.

Returns

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

Examples

readline/main.c, and simple-editline/main.c.

ec_node_int_getval()

int ec_node_int_getval	(	const struct ec_node *	node,
		const char *	str,
		int64_t *	result )

Get the value of a parsed signed integer.

Parameters

node	The integer node.
str	The string to parse.
result	Pointer where the result will be stored on success.

Returns

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

ec_node_uint()

struct ec_node * ec_node_uint	(	const char *	id,
		uint64_t	min,
		uint64_t	max,
		unsigned int	base )

Create an unsigned integer node.

Parameters

id	The node identifier.
min	The minimum valid value (included).
max	The maximum valid value (included).
base	The base to use for parsing. If 0, try to guess from prefix.

Returns

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

ec_node_uint_getval()

int ec_node_uint_getval	(	const struct ec_node *	node,
		const char *	str,
		uint64_t *	result )

Get the value of a parsed unsigned integer.

Parameters

node	The unsigned integer node.
str	The string to parse.
result	Pointer where the result will be stored on success.

Returns

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