I tried to delete DB using dlp_req but no succes.
Sample code is below.
This conduit runs only for my creator/type.
DB should be closed before deleting, so it is closed because I'm not even opening
it.
$retval contains nothing, and $err contains 0x35.
So there was an error deleting DB, but i don't know why.
DB do contains dirty records.

BTW
Why does dlpdeleterecord in dlp_cmd.c uses uid to find record? It takes O(n) for
finding it.
What is the "special argument value" for dlpdeleterecord to mean "delete all
records"?

CODE:
#!/usr/bin/perl
use ColdSync;
use ColdSync::SPC;
use Palm::Zamw;

StartConduit("sync");

my $retval;
$base="dokumen";
($err,@odp)=&dlp_req(0x1a,{ id=>0x20, data=>pack("C a*x",0,$base)});

  for (@odp)
       {
       if ($_->{id} == 0x20)
               {
               $retval=unpack("C",$_->{data});
               }
       else { }
       }
open OUTFILE,">logfile";

print OUTFILE ($retval,"\n");
print OUTFILE ($err,"\n";

close OUTFILE;
EndConduit();
