Hi all, I'm currently using libsmi with Delphi/Windows (I built a DLL using GCC). I am having a strange problem with certain MIBs. When I call smiGetFirstNode(ModuleName, SMI_NODEKIND_ANY) for certain MIBs, the first node structure returned is completely empty other than the OID. The second node returned (after an smiGetNextNode) is a valid node, but is not the node expected - it is actually the 5th node that should be returned. The first OID is also strange as these MIBs are enterprise MIBs and the first OID returned is similar to the following(from example 1): 1.3.6.1.4.1.5591.1.0 where it should be: 1.3.6.1.4.1.5591.1.8.1.2 (See example 1)
The problem only seems to occur where the MIB has a construct like the following from example 1:
downLoad OBJECT IDENTIFIER ::= { downloadIdent 1 } transponderImage OBJECT IDENTIFIER ::= { downloadIdent 2 }
Example 2 does not have these constructs and the first node is returned as expected.
Any ideas? Am I doing something wrong?

dlDownloadDevice OBJECT-TYPE SYNTAX INTEGER ACCESS read-write STATUS mandatory DESCRIPTION "This object defines the device which is to have firmware downloaded.
A value of 1 specifies the transponder. A value of 2 to 256 specifies TIB devices 1 to 255. Values of dlDownloadDevice greater than 256 may be used for non-TIB devices managed by the transponder.
This indexing scheme is used to avoid using an index value of 0 to identify the transponder. This indexing scheme matches that of dlTransponderTable.
Not all transponders support TIB based devices.
There are no restrictions on the value of this object. When dlDownloadControl is set to initiate(1), an invalid value for dlDownloadImage results in the inability to set dlDownloadControl.
This value for this object reverts back to 0 after the end of any download or download error. As valid indices begins at 1, this provides some added security to prevent accidental erasure.
The value of this object should only be changed when dlDownloadStatus is done(6). Attempts to change object during any other state results in termination of the download in progress and an error being recorded. The actions associated with detecting an error are described by Note 4 of the download state diagram presented earlier in the document. The object value will not be cleared and the new value shall be accepted.
The dlDownloadKey does not affect this object.
The default value is 0. This object is volatile." ::= { downLoad 2 }
