29 * Oh, this is hellish.
31 * The CMU SNMP library defines an OID as a sequence of "u_int"s,
32 * unless EIGHTBIT_SUBIDS is defined, in which case it defines
33 * an OID as a sequence of "u_char"s. None of its header files
34 * define EIGHTBIT_SUBIDS, and if a program defines it, that's
35 * not going to change the library to treat OIDs as sequences
36 * of "u_chars", so I'll assume that it'll be "u_int"s.
38 * The UCD SNMP library does the same, except it defines an OID
39 * as a sequence of "u_long"s, by default.
41 * "libsmi" defines it as a sequence of "unsigned int"s.
43 * I don't want to oblige all users of ASN.1 to include the SNMP
44 * library header files, so I'll assume none of the SNMP libraries
45 * will rudely surprise me by changing the definition; if they
46 * do, there will be compiler warnings, so we'll at least be able
49 * This requires that, if you're going to use "asn1_subid_decode()",
50 * "asn1_oid_value_decode()", or "asn1_oid_decode()", you include
51 * "config.h", to get the right #defines defined, so that we properly
