void ldns_dname2canonical (  const ldns_rdf *  rdf  )

Put a dname into canonical fmt - ie. lowercase it Parameters: [in]  rdf  the dname to lowercase Returns: void

ldns_status ldns_dname_cat (  ldns_rdf *  rd1, ldns_rdf *  rd2 )

concatenates rd2 after rd1 (rd2 is copied, rd1 is modified) Parameters: [in]  rd1  the leftside [in]  rd2  the rightside Returns: LDNS_STATUS_OK on success

ldns_rdf* ldns_dname_cat_clone (  ldns_rdf *  rd1, ldns_rdf *  rd2 )

concatenate two dnames together Parameters: [in]  rd1  the leftside [in]  rd2  the rightside Returns: a new rdf with leftside/rightside

bool ldns_dname_is_subdomain (  const ldns_rdf *  sub, const ldns_rdf *  parent )

test wether the name sub falls under parent (i.e. is a subdomain of parent. Parameters: [in]  sub  the name to test [in]  parent  the parent's name Returns: true if sub falls under parent, otherwise false

ldns_rdf* ldns_dname_label (  const ldns_rdf *  rdf, uint8_t  labelpos )

look inside the rdf and if it is an LDNS_RDF_TYPE_DNAME try and retrieve a specific label. The labels are numbered starting from 0 (left most). Parameters: [in]  rdf  the rdf to look in [in]  labelpos  return the label with this number Returns: a ldns_rdf* with the label as name or NULL on error

uint8_t ldns_dname_label_count (  const ldns_rdf *  r  )

count the number of labels inside a LDNS_RDF_DNAME type rdf. Parameters: [in]  *r  the rdf Returns: the number of labels

ldns_rdf* ldns_dname_left_chop (  ldns_rdf *  d  )

chop one label off a dname. so wwww.nlnetlabs.nl, becomes nlnetlabs.nl Parameters: [in]  d  the dname to chop Returns: the remaining dname

ldns_rdf* ldns_dname_new (  uint16_t  s, void *  data )

Create a new dname rdf from a string. Parameters: [in]  s  the size of the new dname [in]  *data  pointer to the actual data Returns: ldns_rdf*

ldns_rdf* ldns_dname_new_frm_data (  uint16_t  size, const void *  data )

Create a new dname rdf from data (the data is copied). Parameters: [in]  size  the size of the data [in]  *data  pointer to the actual data Returns: ldns_rdf*

ldns_rdf* ldns_dname_new_frm_str (  const char *  str  )

Create a new dname rdf. Copies pointers! Parameters: [in]  str  string to use Returns: ldns_rdf*

bool ldns_dname_str_absolute (  const char *  dname_str  )

Checks whether the given dname string is absolute (i.e. ends with a '.') Parameters: [in]  *dname_str  a string representing the dname Returns: true or false
