Hi all!
Supose that I have an UDF that has a BLOB param.
Is there a way to see only a specific byte of that BLOB?
For ex: I want the last byte of that BLOB.
I should do that WITHOUT reading ALL the blob (from the begining), as
it is suggested by the function (in the BLOB structure):
GetSegment : function(Handle:Pointer; Buffer:PChar;
SegmentLen:Integer; var Length:Integer):WordBool; cdecl;
In other words, is there a kind of "seek" function for that blob?
Thanks,
Lucio IP.
