DBus8ByteStruct
An 8-byte struct you could use to access int64 without having int64 support.
Definition dbus-types.h:145
DBus8ByteStruct::second32
dbus_uint32_t second32
second 32 bits in the 8 bytes (beware endian issues)

DBus8ByteStruct::first32
dbus_uint32_t first32
first 32 bits in the 8 bytes (beware endian issues)
Definition dbus-types.h:146
DBusBasicValue
