◆ cql_parser_destroy()

void cql_parser_destroy ( CQL_parser cp )

destroys a CQL parser.

Parameters

cp	CQL parser

This function does nothing if NULL if received.

◆ cql_parser_result()

struct cql_node* cql_parser_result ( CQL_parser cp )

returns the parse tree of the most recently parsed CQL query.

Parameters

cp	CQL parser

Returns: CQL node or NULL for failure

◆ cql_parser_stream()

int cql_parser_stream	(	CQL_parser	cp,
		int()(void client_data)	getbyte,
		void()(int b, void client_data)	ungetbyte,
		void *	client_data
	)

parses CQL query (query stream)

Parameters

cp	CQL parser
getbyte	function which reads one character from stream
ungetbyte	function which unreads one character from stream
client_data	data to be passed to stream functions

Return values

0	success
!=0	failure

This function is similar to cql_parser_string but takes a functions to read each query character from a stream.

The functions pointers getbytes, ungetbyte are similar to that known from stdios getc, ungetc.
