_VOLK_PARSER_COMMON_H

YYCTYPE

#define YYCTYPE   uint8_t

TTL is UTF-8 encoded.

char should be considered to be UTF-8 throughout this library, however, setting YYCTYPE to char generates case labels outside of the char range.

VOLK_ttl_parse_doc()

VOLK_rc VOLK_ttl_parse_doc	(	FILE *	fh,
		const char *	sh,
		VOLK_Graph **	gr,
		size_t *	ct,
		char **	err )

Parse an RDF document in Turtle format.

Either an open file handle or an in-memory string can be passed for parsing.

Parameters

[in]	fh	Turtle doc file handle. Exclusive with sh.
[in]	sh	Turtle doc string handle. Exclusive with fh.
[out]	gr	Pointer to a graph handle to be created. The new graph will have a random UUID URN.
[out]	ct	If not NULL it is populated with the number of triples parsed. This may be more than the triples in the resulting graph.
[out]	err	String handle to be populated with an error message.

Returns

VOLK_OK on success, VOLK_VALUE_ERR if a parsing error was encountered. On error, err will contain the error message.
