#define CALLOC	(		S,
			T,
			N
	)

Value:

S = calloc(sizeof(T), N);\
        if ((S) == NULL) {\
          fprintf(stderr,"file %s, line %lu: calloc(%lu) failed\n",\
                  __FILE__,(Showuint) __LINE__,\
                  (Showuint) (sizeof(T) * (size_t) (N)));\
          exit(EXIT_FAILURE);\
        }

Allocs a new block of memory and sets all its bits to zero.

Parameters

[out]	S	pointer to the new allocated memory.
[in]	T	type of the objects that will be stored in this memory area.
[in]	N	number of objects of type T that will be possible to store in the new memory.
