bit operators

Hello! I have an idea to write common filters like define RF_REDISTRIBUTE_CONNECTED 0x10 define RF_REDISTRIBUTE_STATIC 0x20 ..... protocol ospf main_ospf { export where f_main_ospf_e(RF_REDISTRIBUTE_CONNECTED | RF_REDISTRIBUTE_STATIC); ..... } function f_main_ospf_e(int flags) { if(source ~ [RTS_STATIC, RTS_STATIC_DEVICE] && (flags & RF_REDISTRIBUTE_STATIC) ........ } Unfortunatelly there are not bit operators :( But may be there is another way?
