#ifndef MACROS_NULLCHECK_H_
#define MACROS_NULLCHECK_H_
#include <assert.h>
#define NULLCHECK(x) assert(x != (void *) 0);
#endif
If I used the above style as a template for declaring Macros, what provisos would you have?
put parenthesis around the argument (it prevents problems when passing expressions)
don’t put ; at the end (the use will be more natural)
#define NULLCHECK(x) assert((x) != (void*)0)
