does the underscore or double underscore mean something in c++?
Posted on 2003-03-16
there are some variables that have some leading underscores (_) or (__) infront of a variable...does that mean anything?
I am not looking for answers like, leading underscores for a variable name is valid. I understnad that...but i have seen some codes, for example, look below.
__declspec(dllexport) CString SayHello (CString strName);
__declspec(dllexport) virtual ~CMyClass();
why do they design declspecto have 2 leading underscores? There are some with just 1 leading underscores...
from the books i read for c++, i dont see any explanation of this...
by the way, i asked a question last week, but didnt close it yet, i have an answer to accept...but i cant find that question...how do i see what are the qeustions i have asked in experts-exchange.com??
