ldns_fget_token()

ssize_t ldns_fget_token	(	FILE *	f,
		char *	token,
		const char *	delim,
		size_t	limit
	)

returns a token/char from the stream F.

This function deals with ( and ) in the stream, and ignores them when encountered

Parameters

[in]	*f	the file to read from
[out]	*token	the read token is put here
[in]	*delim	chars at which the parsing should stop
[in]	*limit	how much to read. If 0 the builtin maximum is used

Returns

0 on error of EOF of the stream F. Otherwise return the length of what is read

ldns_fget_token_l()

ssize_t ldns_fget_token_l	(	FILE *	f,
		char *	token,
		const char *	delim,
		size_t	limit,
		int *	line_nr
	)

returns a token/char from the stream F.

This function deals with ( and ) in the stream, and ignores when it finds them.

Parameters

[in]	*f	the file to read from
[out]	*token	the token is put here
[in]	*delim	chars at which the parsing should stop
[in]	*limit	how much to read. If 0 use builtin maximum
[in]	line_nr	pointer to an integer containing the current line number (for debugging purposes)

Returns

0 on error of EOF of F otherwise return the length of what is read

ldns_bget_token()

ssize_t ldns_bget_token	(	ldns_buffer *	b,
		char *	token,
		const char *	delim,
		size_t	limit
	)

returns a token/char from the buffer b.

This function deals with ( and ) in the buffer, and ignores when it finds them.

Parameters

[in]	*b	the buffer to read from
[out]	*token	the token is put here
[in]	*delim	chars at which the parsing should stop
[in]	*limit	how much to read. If 0 the builtin maximum is used

Returns

0 on error of EOF of b. Otherwise return the length of what is read
