function as a macro

Dear

i want to know can at what extent we can make a complex function as a macro



for ex.

getFromString(CString s, LPCTSTR delemiter)
{

CString temp;

int m= s.findof(delemiter);
if(m!=-1)
temp= s.mid(m);


}

 

Well, this particular one would be like this:


#define GET_FROM_STRING(s, delim) \
{\
CString temp;\

int m= s.findof(delemiter);\
if(m!=-1)\
temp= s.mid(m);\
}


Note the \ symbols - they concatenate physical source lines.
But making a macro out of such a funvtion is a horrible idea, because macros don't have scope, their parameters don't have types and, of course many surprising results can occur due to literal text substitution.

 

Thanks very much

 

Thanks again to LordN3mrod for this valuable tips i m going to do this mistake

 

I will repeat myself, DON"T use a macro unless you have to. In this particular case an inline function (a function delcared with the keyword inline, and defined in the same ".h" file) is a superior alternative.
