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.

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.

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.
