Newline inside macro expansion

[Bansidhar Arvind Deshpande - CTD, Chennai.]

Hi all,

This may be simple C preprocessor question. 

I want to write a macro which should have '\n' in its expansion.

e.g. 

#define MAC(a,b) ........

If I call this macro as MAC(param1,param2) its expansion should be
as follows

if(a == param1) 
b = param2;

Hence, I want '\n' (newline character) in macro expansion after if(a ==
param1) .

How can I write macro MAC so as to achieve above functionality.

Thanks,
