Parameters:

info - Sockaddr class to fill

sa - Structure pointer

info

public static long info(java.lang.String hostname,
                        int family,
                        int port,

                 throws java.lang.Exception

Create apr_sockaddr_t from hostname, address family, and port.

Parameters:

hostname - The hostname or numeric address string to resolve/parse, or NULL to build an address that corresponds to 0.0.0.0 or ::

family - The address family to use, or APR_UNSPEC if the system should decide.

port - The port number.

flags - Special processing flags:

       APR_IPV4_ADDR_OK          first query for IPv4 addresses; only look
                                 for IPv6 addresses if the first query failed;
                                 only valid if family is APR_UNSPEC and hostname
                                 isn't NULL; mutually exclusive with
                                 APR_IPV6_ADDR_OK
       APR_IPV6_ADDR_OK          first query for IPv6 addresses; only look
                                 for IPv4 addresses if the first query failed;
                                 only valid if family is APR_UNSPEC and hostname
                                 isn't NULL and APR_HAVE_IPV6; mutually exclusive
                                 with APR_IPV4_ADDR_OK
 

p - The pool for the apr_sockaddr_t and associated storage.

Returns:

The new apr_sockaddr_t.

Throws:

java.lang.Exception

getnameinfo

public static java.lang.String getnameinfo(long sa,
                                           int flags)

Look up the host name from an apr_sockaddr_t.

Parameters:

sa - The apr_sockaddr_t.

flags - Special processing flags.

Returns:

The hostname.

getip

public static java.lang.String getip(long sa)

Return the IP address (in numeric address string format) in an APR socket address. APR will allocate storage for the IP address string from the pool of the apr_sockaddr_t.

Parameters:

sa - The socket address to reference.

Returns:

The IP address.

getservbyname

public static int getservbyname(long sockaddr,
                                java.lang.String servname)

Given an apr_sockaddr_t and a service name, set the port for the service

Parameters:

sockaddr - The apr_sockaddr_t that will have its port set

servname - The name of the service you wish to use

Returns:

APR status code.

get

public static long get(int which,
                       long sock)
                throws java.lang.Exception

Return an apr_sockaddr_t from an apr_socket_t

Parameters:

which - Which interface do we want the apr_sockaddr_t for?

sock - The socket to use

Returns:

The returned apr_sockaddr_t.

Throws:

java.lang.Exception

equal

public static boolean equal(long a,
                            long b)

See if the IP addresses in two APR socket addresses are equivalent. Appropriate logic is present for comparing IPv4-mapped IPv6 addresses with IPv4 addresses.

Parameters:

a - One of the APR socket addresses.

b - The other APR socket address. The return value will be True if the addresses are equivalent.
