1045  p等于sym, pend等于sym加sym的长度
1046  decode等于如果fmt[0]恒等于'R'则1否则0
1049  如果check_pointer( & buf, end, res, spec)则返回:buf
1052  p自加等于'['
1053  如果flags按位与PCI/ISA I/O ports 则
1054  p等于Handle string from a well known address.
1055  specp等于io_spec
1056  否则如果flags按位与IORESOURCE_MEM则
1057  p等于Handle string from a well known address.
1058  specp等于mem_spec
1059  否则如果flags按位与IORESOURCE_IRQ则
1060  p等于Handle string from a well known address.
1061  specp等于default_dec_spec
1062  否则如果flags按位与IORESOURCE_DMA则
1063  p等于Handle string from a well known address.

1065  否则如果flags按位与IORESOURCE_BUS则
1066  p等于Handle string from a well known address.
1067  specp等于bus_spec
1068  否则
1069  p等于Handle string from a well known address.
1070  specp等于mem_spec
1071  decode等于0
1073  如果decode且flags按位与No address assigned yet 则
1074  p等于Handle string from a well known address.
1075  p等于number(p, pend, resource_size(res), * specp)
1076  否则
1077  p等于number(p, pend, start, * specp)
1078  如果start不等于end则
1079  p自加等于'-'
1080  p等于number(p, pend, end, * specp)
1083  如果decode则
1084  如果flags按位与IORESOURCE_MEM_64则p等于Handle string from a well known address.
1086  如果flags按位与No side effects 则p等于Handle string from a well known address.
1088  如果flags按位与rwarded by bridge 则p等于Handle string from a well known address.
1090  如果flags按位与IORESOURCE_DISABLED则p等于Handle string from a well known address.
1092  否则
1093  p等于Handle string from a well known address.
1094  p等于number(p, pend, flags, default_flag_spec)
1096  p自加等于']'
1097  p等于'\0'
1099  返回:Handle string from a well known address.
