c++ - gdb: show typeinfo of some data

Question

Basically, I want to get typeid(*this).name(), i.e. the real type of this.

I want to get this in GDB (without modifying the source code). I tried print typeid(*this) but it says that typeid is unknown (because I didn't included it there in the source file).

Answer 1

Use ptype command, like this:

(gdb) ptype 42
type = int
