int nl_addr_resolve ( struct nl_addr *  addr,
char *  host,
size_t  hostlen 
)

Resolve abstract address object to a name using getnameinfo().

  • addr Abstract address object.
  • host Destination buffer for host name.
  • hostlen Length of destination buffer.
Resolves the abstract address to a name and writes the looked up result into the host buffer. getnameinfo() is used to perform the lookup and is put into NI_NAMEREQD mode so the function will fail if the lookup couldn't be performed.

Returns:
0 on success or a negative error code.
