## Define Documentation

#define ACE_align_binary | ( | ptr,
|  | alignment |  | ) | ((ptr + ((ptrdiff_t)((alignment)-1))) & (~((ptrdiff_t)((alignment)-1))))

  | Return the next integer aligned to a required boundary. Parameters:
  | ptr | the base pointer
  | alignment | the required alignment

#define ACE_INLINE inline

#define ACE_MALLOC_FUNC ::malloc

#define ACE_NEW | ( | POINTER,
|  | CONSTRUCTOR |  | ) |

| Value:

       } while (0)

#define ACE_NEW_NORETURN | ( | POINTER,
|  | CONSTRUCTOR |  | ) |

| Value:
    do { POINTER = new CONSTRUCTOR; \

       } while (0)

#define ACE_ptr_align_binary | ( | ptr,
|  | alignment |  | ) | ((char *) ACE_align_binary (((ptrdiff_t) (ptr)), (alignment)))

| Return the next address aligned to a required boundary.

#define ACE_REALLOC_FUNC ::realloc
