Quick parse segments from a string.

The provided callback is invoked for every segment of parsed input, where each segments is separated by either a newline or semicolon (;), respectively depending on whether a client command is being parsed or not. If the flag CYPHER_PARSE_ONLY_STATEMENTS is set, then only semicolons will be used for delimiting segments, and client commands will not be parsed.

Parameters

[s]	The string to parse.
[callback]	The callback to be invoked for each parsed segment.
[userdata]	A pointer that will be provided to the callback.
[flags]	A bitmask of flags to control parsing.

Returns

0 on success, or -1 on failure (errno will be set).

Check if the quick parse encountered the end of the input.

Indicates if the segment was terminated by to the end of the input.

Parameters

		cypher_parser_config_t *	config,
		uint_fast32_t	flags
	)

Parse segments from a string.

The provided callback is invoked for every segment of parsed input, where each segments is separated by either a newline or semicolon (;), respectively depending on whether a client command is being parsed or not. If the flag CYPHER_PARSE_ONLY_STATEMENTS is set, then only semicolons will be used for delimiting segments, and client commands will not be parsed.

The segment will be released after the callback is complete, unless retained using cypher_parse_segment_retain().

Parameters

[s]	The string to parse.
[n]	The size of the string.
[callback]	The callback to be invoked for each parsed segment.
[userdata]	A pointer that will be provided to the callback.
