typedef struct mib_entry { /* << SNMP-MIB Entry Info >> */ U8 Type; /* Object Type */ U8 OidLen; /* Object ID length */ U8 Oid[MIB_OIDSZ]; /* Object ID value */ U8 ValSz; /* Size of a Variable */ void *Val; /* Pointer to a variable */ void (*cb_func)(int mode); } MIB_ENTRY;
Why OID has type unsigned char? Numbers in OID can be more than 256.
My guess is the array of U8's is supposed to hold an OID encoded in DER. By the way, DER is the encoding used to send them on the wire, so it would make a lot of sense to use it here.
Can you tell me how to fill structure with MIB variable which has OID "1.3.6.1.4.1.31036.50.1.1.0"?
11, {OID0(1,3), 6, 1, 4, 1, 242, 60, 50, 1, 1, 0},
I'm sorry, that was wrong, here is a correct OID encoding:
12, {OID0(1,3), 6, 1, 4, 1, 129, 242, 60, 50, 1, 1, 0},
