Heap

Description

Type-safe and null-pointer-aware heap operations.

Collaboration diagram for Heap:

C-style Allocation ...
#define	MALLOC(T, N)   (T*) malloc (sizeof (T) * (N))
	Allocate an array of N objects of type T (type-safe)
#define	REALLOC(T, P, N)   (T*) realloc (P, sizeof (T) * (N))
	Reallocate an array of N objects of type T (type-safe)
#define	SETP(P, X)   { if (P) free (P); P = (X); }
	Replace P with a new object/array, eventually free'ing the old one.
#define	FREEP(P)   SETP(P, NULL)
	Free object/array P and set P = NULL, but only if P was != NULL.

C++-style Allocation ...
#define	SETO(O, X)   { if (O) delete O; O = (X); }
	Replace O with a new object, eventually deleting the old one.
#define	FREEO(O)   SETO(O, NULL)
	Free object O, but only if O != NULL
#define	SETA(A, X)   { if (A) delete [] A; A = (X); }
	Replace A with a new array, eventually deleting the old one.
#define	FREEA(A)   SETA(A, NULL)
	Free array A, but only if A != NULL
