Say I have a simple class like the one below:
class Foo
{
public:
Foo(){};
protected:
int meth1( void ){return 0;};
public:
int var1;
};
Compiled with MSVC and parsing the corresponding PDB via the DbgHelp API, I can iterate over the children and parse out the methods and variables fine, but I am unable to figure out how I determine the access specifier for a given child. My code looks something like this:
// The symbol tag for 'index' is a SymTagEnum::SymTagBaseClass
DWORD item_count;
if( !::SymGetTypeInfo( process, base_address, index, TI_GET_CHILDRENCOUNT, &item_count ) )
break;
if( item_count > 0 )
{
TI_FINDCHILDREN_PARAMS * item_indexs = new TI_FINDCHILDREN_PARAMS[item_count];
item_indexs->Count = item_count;
item_indexs->Start = 0;
if( ::SymGetTypeInfo( process, base_address, index, TI_FINDCHILDREN, item_indexs ) )
{
for( DWORD i=0 ; i<item_count ; i++ )
{
DWORD item_tag;
if( !::SymGetTypeInfo( process, base_address, item_indexs->ChildId[i], TI_GET_SYMTAG, &item_tag ) )
break;
DWORD item_type_index;
if( !::SymGetTypeInfo( process, base_address, item_indexs->ChildId[i], TI_GET_TYPEID, &item_type_index ) )
break;
// XXX: How to discover the access specifier (public, private, protected) for
// the class method/variable at 'item_type_index'?
switch( item_tag )
{
case SymTagEnum::SymTagFunction:
{
// parse out the class method at 'item_type_index'
break;
}
case SymTagEnum::SymTagData:
{
// parse out the class variable at 'item_type_index'
break;
}
default:
{
break;
}
}
}
}
}
Is it possible to determine the access specifiers (public, private, protected) for a classes children via the DbgHelp API, and if so, how?
