Hi Doug,

You're right in general of course, but I still think macros are handy for
lots of things like:

#define LogCriticalEvent(val) theApp.LogEventObject._LogEvent(#val, val,

Sees user identifier starting with underscore+capital and shudders...

_T(__FUNCTION__), __LINE__, 0, true)

Actually, those are Windows define functions. _T is a define defined in
some windows header as is __FUNCTION__ and __LINE__
None of his defines/functions/macros are declaring variables with leading
underscores, he's just using library ones.



Where this would be more difficult to do in a function. I kind of miss
being able to do this sort of thing when writing C# code :o)

Tom

Hi,

As I can define something like

#define ABC(x) if(x){x = NULL;}

but how can I define something similar but the code block is relatively
large (like several lines testing different cases, etc)?

Thanks,
Alan

FWIW, in C++, you should almost always write inline functions instead of
macros.
