		size_t *	len
	)

Convert text string into dname wireformat, mallocless, with user buffer.

Parameters

len	length of the buffer on input, length of the result on output.

Returns

0 on success, otherwise an error.

Same as sldns_str2wire_dname_buf, but concatenates origin if the domain name is relative (does not end in '.

').

Parameters

Convert text RR to wireformat, with user buffer.

Parameters

str	the RR data in text presentation format.
rr	the buffer where the result is stored into. This buffer has the wire-dname(uncompressed), type, class, ttl, rdatalen, rdata. These values are probably not aligned, and in network format. Use the sldns_wirerr_get_xxx functions to access them safely. buffer size LDNS_RR_BUF_SIZE is suggested.
len	on input the length of the buffer, on output the amount of the buffer used for the rr.
dname_len	if non-NULL, filled with the dname length as result. Because after the dname you find the type, class, ttl, rdatalen, rdata.
default_ttl	TTL used if no TTL available.
origin	used for origin dname (if not NULL)
origin_len	length of origin.
prev	used for prev_rr dname (if not NULL)
prev_len	length of prev.

Returns

0 on success, an error on failure.

Parameters

rr	the RR in wire format.
len	rr length.
dname_len	dname length to skip.

Returns

rdata length in host byteorder If the rdata length is larger than the rr-len allows, it is truncated. So, that it is safe to read the data length returned from this function from the rdata pointer of sldns_wirerr_get_rdata.

Read one RR from zonefile with buffer for the data.

Parameters

in	file that is read from (one RR, multiple lines if it spans them).
rr	this is malloced by the user and the result is stored here, if an RR is read. If no RR is read this is signalled with the return len set to 0 (for ORIGIN, TTL directives). The read line is available in the rr_buf (zero terminated), for $DIRECTIVE style elements.
len	on input, the length of the rr buffer. on output the rr len. Buffer size of 64k should be enough.
dname_len	returns the length of the dname initial part of the rr.
parse_state	pass a pointer to user-allocated struct. Contents are maintained by this function. If you pass NULL then ORIGIN and TTL directives are not honored. You can start out with a particular origin by pre-filling it. otherwise, zero the structure before passing it. lineno is incremented when a newline is passed by the parser, you should initialize it at 1 at the start of the file.

Returns

0 on success, error on failure.
