ldns_rr_new() creates a new rr structure.
Returns ldns_rr *

ldns_rr_new_frm_type() creates a new rr structure, based on the given type. alloc enough space to hold all the rdf's

ldns_rr_new_frm_str() creates an rr from a string. The string should be a fully filled-in rr, like ownername &lt;space&gt; TTL &lt;space&gt; CLASS &lt;space&gt; TYPE &lt;space&gt; RDATA.
n: the rr to return
str: the string to convert
default_ttl: default ttl value for the rr. If 0 DEF_TTL will be used
origin: when the owner is relative add this. The caller must ldns_rdf_deep_free it.
prev: the previous ownername. if this value is not NULL, the function overwrites this with the ownername found in this string. The caller must then ldns_rdf_deep_free it.
Returns a status msg describing an error or LDNS_STATUS_OK

ldns_rr_new_frm_fp() creates a new rr from a file containing a string.
rr: the new rr
fp: the file pointer to use
default_ttl: pointer to a default ttl for the rr. If NULL DEF_TTL will be used the pointer will be updated if the file contains a $TTL directive
origin: when the owner is relative add this the pointer will be updated if the file contains a $ORIGIN directive The caller must ldns_rdf_deep_free it.
prev: when the owner is whitespaces use this as the * ownername the pointer will be updated after the call The caller must ldns_rdf_deep_free it.
Returns a ldns_status with an error or LDNS_STATUS_OK

ldns_rr_free() frees an RR structure
*rr: the RR to be freed
Returns void

ldns_rr_print() Prints the data in the resource record to the given file stream (in presentation format)

output: the file stream to print to
rr: the resource record to print
Returns void
