Uncompress a DNS compressed name.
|
||
|
|
||
|
The containing dns message is required because the compressed encoding
|
||
|
and reference suffixes present elsewhere in the packet.
|
||
|
|
||
|
If name is less than `dst_len` characters long, the remainder
|
||
|
of `dst` is terminated with `\0' characters. Otherwise, `dst` is not
|
||
|
*terminated.
|
||
|
|
||
|
If `dst_len` is 0 `dst` can be NULL.
|
||
|
Return the uncompressed name length.
