/*%<
* Use the system resolver to get the addresses associated with a hostname.
* If successful, the number of addresses found is returned in 'addrcount'.
* If a hostname lookup is performed and addresses of an unknown family is
* seen, it is ignored. If more than 'addrsize' addresses are seen, the
* first 'addrsize' are returned and the remainder silently truncated.
*
* This routine may block. If called by a program using the isc_app
* framework, it should be surrounded by isc_app_block()/isc_app_unblock().
*
* Requires:
*\li 'hostname' is not NULL.
*\li 'addrs' is not NULL.
*\li 'addrsize' > 0
*\li 'addrcount' is not NULL.
*
*
* Returns:
*\li #ISC_R_SUCCESS
*\li #ISC_R_NOTFOUND
*\li #ISC_R_FAMILYNOSUPPORT - 'hostname' is an IPv6 address, and IPv6 is
* not supported.
