Function Documentation

◆ node_parse_one()

struct ExpandoNode * node_parse_one	(	const char *	str,
		NodeTextTermFlags	term_chars,
		const struct ExpandoDefinition *	defs,
		const char **	parsed_until,
		struct ExpandoParseError *	err
	)

Parse a single Expando from a format string.

Parameters

[in]	str	String to parse
[in]	term_chars	Terminator characters, e.g. NTE_GREATER
[in]	defs	Expando definitions
[out]	parsed_until	First character after parsed string
[out]	err	Buffer for errors

Return values

ptr	Expando Node
