FFI::C::Union - Union data instance for FFI
=head1 VERSION
version 0.15
=head1 SYNOPSIS
use FFI::C::UnionDef;
my $def = FFI::C::UnionDef->new(
name => 'anyint_t',
class => 'AnyInt',
members => [
u8 => 'uint8',
u16 => 'uint16',
u32 => 'uint32',
],
);
my $int = AnyInt->new({ u8 => 42 });
printf "0x%x\n", $int->u32; # 0x2a on Intel
=head1 DESCRIPTION
This class represents an instance of a C C<union>. This class can be created using
C<new> on the generated class, if that was specified for the L<FFI::C::UnionDef>,
or by using the C<create> method on L<FFI::C::UnionDef>.
For each member defined in the L<FFI::C::UnionDef> there is an accessor for the
L<FFI::C::Union> instance.
=head1 CONSTRUCTOR
=head2 new
FFI::C::UnionDef->new( class => 'User::Union::Class', ... );
my $instance = User::Union::Class->new;
Creates a new instance of the C<union>.
