◆ sldns_wire2str_pkt_buf()

int int sldns_wire2str_pkt_buf ( uint8_t *  data,
size_t  data_len,
char *  str,
size_t  str_len 
)

Convert wireformat packet to a string representation with user buffer It appends every RR with default comments.

For more formatter options use the function: TBD(TODO)

Parameters
datawireformat packet data (starting at ID bytes).
data_lenlength of packet.
strthe string buffer for the output. If you pass NULL as the str the return value of the function is the str_len you need for the entire packet. It does not include the 0 byte at the end.
str_lenthe size of the string buffer. If more is needed, it'll silently truncate the output to fit in the buffer.
Returns
the number of characters for this element, excluding zerobyte. Is larger or equal than str_len if output was truncated.

◆ sldns_wire2str_pkt_scan()

int sldns_wire2str_pkt_scan ( uint8_t **  data,
size_t *  data_len,
char **  str,
size_t *  str_len 
)

Scan wireformat packet to a string representation with user buffer It appends every RR with default comments.

For more formatter options use the function: TBD(TODO)

Parameters
datawireformat packet data (starting at ID bytes).
data_lenlength of packet.
strthe string buffer for the output.
str_lenthe size of the string buffer.
Returns
number of characters for string. returns the number of characters that are needed (except terminating null), so it may return a value larger than str_len. On error you get less output (i.e. shorter output in str (null terminated)) On exit the data, data_len, str and str_len values are adjusted to move them from their original position along the input and output for the content that has been consumed (and produced) by this function. If the end of the output string is reached, *str_len is set to 0. The output string is null terminated (shortening the output if necessary). If the end of the input is reached *data_len is set to 0.
