Seems to be a question of no importance, but I'm just curious: Is there a deeper meaning of the preceeding (single/double) ?-marks, @-signs or __ underscores in these different call instructions?
call ??2@YAPAXI@Z
call ??0CAdviseObject@CBLObject@@QAE@PAUIDispatch@@PAVCBLInstance@@@Z
call ?StartAutoReconnect@CBLObject@@IAEXIH@Z
call @__security_check_cookie@4
call __SEH_epilog
The leading ? identifies a C++ name mangled symbol. Two ?? signify operators, constructors, destructors, constant strings, and various compiler generator functions. For example ??0 is a constructor. This site has a good breakdown of the mangling pieces used by MSVC.
A leading underscore _ can either be due to the calling convention or due to the CRT/compiler identification standard. They will prefix all of their symbols with two leading underscores __ as a way to help prevent name collisions:
In Microsoft C++, identifiers with two leading underscores are reserved for compiler implementations.
These are so-called "mangled" or "decorated" names. You can use undname utility from Visual Stduio to demangle them:
void * __cdecl operator new(unsigned int)
public: __thiscall CBLObject::CAdviseObject::CAdviseObject(struct IDispatch *,cl
ass CBLInstance *)
protected: void __thiscall CBLObject::StartAutoReconnect(unsigned int,int)
