Function Documentation

parse_fork_abandon()

void parse_fork_abandon

(

ParseFork *

fork

)

#include <include/parser_fork.h>

Mark a fork as abandoned (pruned).

Parameters

fork	The fork to abandon.

parse_fork_complete()

void parse_fork_complete	(	ParseFork *	fork,
		void *	result,
		void(*)(void *)	free_fn
	)

#include <include/parser_fork.h>

Mark a fork as completed with the given semantic result.

Sets status to FORK_COMPLETED and stores the result pointer.

Parameters

fork	The fork to complete.
result	Semantic action output.
free_fn	Destructor for result (NULL to use free()).

parse_fork_fail()

void parse_fork_fail

(

ParseFork *

fork

)

#include <include/parser_fork.h>

Mark a fork as failed.

Parameters

fork	The fork that failed.

parse_fork_get_parser()

void * parse_fork_get_parser

(

ParseFork *

fork

)

#include <include/parser_fork.h>

Get a mutable pointer to the cloned yyParser inside a fork.

The returned pointer is valid until free_parse_fork() is called.

Parameters

fork	The fork to access.

Returns

Pointer to the cloned yyParser, or NULL if fork is NULL or has no cloned state.

parse_fork_get_snapshot()

struct ParserSnapshot * parse_fork_get_snapshot

(

const ParseFork *

fork

)

#include <include/parser_fork.h>

Get the snapshot associated with a fork.

Parameters

fork	The fork to query.

Returns

Snapshot pointer, valid for the fork's lifetime.
