       DNS cache management functions.

intwget_dns_cache_init(wget_dns_cache**cache)Parameterscache Pointer to return newly allocated and initialized wget_dns_cache instance

       Returns
           WGET_E_SUCCESS if OK, WGET_E_MEMORY if out-of-memory or WGET_E_INVALID if the mutex initialization
           failed.

       Allocates and initializes a wget_dns_cache instance.

   voidwget_dns_cache_free(wget_dns_cache**cache)Parameters[in/out] cache Pointer to wget_dns_cache instance that will be freed and NULLified.

       Free the resources allocated by wget_dns_cache_init().

   structaddrinfo*wget_dns_cache_get(wget_dns_cache*cache,constchar*host,uint16_tport)Parameterscache A wget_dns_cache instance, created by wget_dns_cache_init().
           host Hostname to look up
           port Port to look up

       Returns
           The cached addrinfo structure or NULL if not found

   intwget_dns_cache_add(wget_dns_cache*cache,constchar*host,uint16_tport,structaddrinfo**addrinfo)Parameterscache A wget_dns_cache instance, created by wget_dns_cache_init().
           host Hostname part of the key
           port Port part of the key
           [in/out] addrinfo Addrinfo structure to cache, returns cached addrinfo

       Returns
           WGET_E_SUCCESS on success, else a WGET_E_* error value

       This functions adds addrinfo to the given DNS cache cache.

       If an entry for [host,port] already exists, addrinfo is free'd and replaced by the cached entry. Do not
       free addrinfo yourself - this will be done when the whole cache is freed.
