Could someone tell me rough ideas of how Vimal> this is stored in the executable, and how to dump this? Usually it is stored in DWARF format. See http://dwarfstd.org/ Iterating over all the types, in gdb, is not trivial. It could be done but you will have to write some C code to do it. The 7 dwarves project would be an ok place to start for this though. pahole nearly does it already. Tom
