Try writing NULL in all caps. AFAIK most definitions of NULL are done
all in upper case letters. If I remember correctly NULL is normally
defined thus: 
 
 
NULL definition is always in capital letters.
 
#define NULL (void*) 0; 
 
 
It depends on the language. For C it is usually the above (without the
';'). For C++ the best definition of NULL is
 
#define NULL 0 
 

Or better: const int NULL=0;
 
 
 But the best in C++ is to use 0 directly.
 
Reference: Paragraph 5.1.1 on page 88 of "The C++ Prrogramming Language"
3rd Edition or Special Edition.
