=head2 C<:socket>

  use APR::Const -compile => qw(:socket);

The C<:socket> group is for the
C<L<APR::Socket|docs::2.0::api::APR::Socket>> object constants, in
methods C<L<opt_get|docs::2.0::api::APR::Socket/C_opt_get_>> and
C<L<opt_set|docs::2.0::api::APR::Socket/C_opt_set_>>.

The following section discusses in detail each of the C<:socket>
constants.




=head3 C<APR::Const::SO_DEBUG>

Possible values:

XXX

=over

=item since: 2.0.00

=back

Turns on debugging information




=head3 C<APR::Const::SO_DISCONNECTED>

Queries the disconnected state of the socket.  (Currently only used on
Windows)

Possible values:

XXX

=over

=item since: 2.0.00

=back






=head3 C<APR::Const::SO_KEEPALIVE>

=over

=item since: 2.0.00

=back







=head3 C<APR::Const::SO_NONBLOCK>

Turns blocking IO mode on/off for socket.

Possible values:

  1 nonblocking
  0 blocking

For example, to set a socket to a blocking IO mode:

  use APR::Socket ();
  use APR::Const    -compile => qw(SO_NONBLOCK);
  ...
  if ($socket->opt_get(APR::Const::SO_NONBLOCK)) {
      $socket->opt_set(APR::Const::SO_NONBLOCK => 0);
  }

You don't have to query for this option, before setting it. It was
done for the demonstration purpose.

the error variable XXXXXX.

The following section discusses in detail each of the available
C<:status> constants.




=head3 C<APR::Const::TIMEUP>

The operation did not finish before the timeout.

=over

=item since: 2.0.00

=back

Due to possible variants in conditions matching C<TIMEUP>, 
for checking error codes against this you most likely want to use the

function instead.














=head2 C<:table>
