◆ cql_parser_result()

struct cql_node * cql_parser_result ( CQL_parser cp)

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

Parameters
cpCQL parser
Returns

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

parses CQL query (query stream)

Parameters
cpCQL parser
getbytefunction which reads one character from stream
ungetbytefunction which unreads one character from stream
client_datadata to be passed to stream functions
Return values
0success
!=0failure

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.
