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 pre‐ sentation format) output: the file stream to print to rr: the resource record to print Returns void
