NAME

ldns_rr_new, ldns_rr_new_frm_type, ldns_rr_new_frm_str, ldns_rr_new_frm_fp, ldns_rr_free, ldns_rr_print - ldns_rr creation, destruction and printing

#include <stdint.h>
#include <stdbool.h>

ldns_rr* ldns_rr_new(void);

ldns_rr* ldns_rr_new_frm_type(ldns_rr_type t);

ldns_status ldns_rr_new_frm_str(ldns_rr **n, const char *str, uint32_t default_ttl, const ldns_rdf *origin, ldns_rdf **prev);

ldns_status ldns_rr_new_frm_fp(ldns_rr **rr, FILE *fp, uint32_t *default_ttl, ldns_rdf **origin, ldns_rdf **prev);

void ldns_rr_free(ldns_rr *rr);

void ldns_rr_print(FILE *output, const ldns_rr *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 fille-in rr, like ownername <space> TTL <space> CLASS <space> TYPE <space> RDATA. .br n: the rr to return .br str: the string to convert .br default_ttl: default ttl value for the rr. If 0 DEF_TTL will be used .br origin: when the owner is relative add this. The caller must ldns_rdf_deep_free it. .br 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. .br 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. .br rr: the new rr .br fp: the file pointer to use .br 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 .br 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. .br 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. .br Returns a ldns_status with an error or LDNS_STATUS_OK

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

ldns_rr_print(): Prints the data in the resource record to the given file stream (in presentation format)
.br output: the file stream to print to .br rr: the resource record to print .br Returns void
