borland c++ tpid

[nino]

I hope I wouldn't get flamed for this but I haven't been able to find useful information regarding the tpid* structures related to borland c++ compilers' rtti. IDA recognizes them in disassemblies of object modules due to VIRDEF records but not in executables. Besides because they're actually meta-structures several fields are left out. I find hard to believe this info is not on the net. The info in typeinfo.h in C++ Builder is scarce (compared to Delphi's typeinfo.pas). Any info regarding these rtti structures is welcome.
