C++ (Cpp) CL_init Examples

Example #1

File: mm.c Project: NguyenTrav/mmalloc

//
// mm_init - Initialize the memory manager
//
int mm_init(void)
{
  CL_init(&free_list);

  // Create empty heap
  if ((heap_listp = mem_sbrk(4*WSIZE)) == (void *)-1){
    return -1;
  }

  //alignment padding
  PUT(heap_listp, 0);
  // prologue header
  PUT(heap_listp + (WSIZE), PACK(DSIZE, 1));
  //prologue footer
  PUT(heap_listp + (DSIZE), PACK(DSIZE, 1));
  //epilogue header
  PUT(heap_listp + (3*WSIZE), PACK(0, 1));
  heap_listp += (DSIZE);

  //extend empty heap with free block of CHUNKSIZE byes
  if (extend_heap(CHUNKSIZE/WSIZE) == NULL){
    return -1;
  }
  return 0;
}

Example #2

File: mm.c Project: Boraz/CSCI-2400

//
// mm_init - Initialize the memory manager
//
int mm_init(void)
{
	CL_init(&free_list);
	
	if ((heap_listp = mem_sbrk(4*WSIZE)) == (void *)-1) { // heap start
		return -1;
    }
    
    PUT(heap_listp, 0);
    PUT(heap_listp + (WSIZE), PACK(DSIZE, 1));
    PUT(heap_listp + (DSIZE), PACK(DSIZE, 1));
    PUT(heap_listp + (3 * WSIZE), PACK(0, 1));
    heap_listp += (DSIZE);
    
    if (extend_heap(CHUNKSIZE / WSIZE) == NULL) {
		return -1;
	}
	
	return 0;
}
