C++ (Cpp) pn_hashcode Examples

Example #1

File: object.c Project: MZDN/qpid-proton

static void test_hashcode(void)
{
  static pn_class_t clazz = PN_CLASS(hashcode);
  void *obj = pn_class_new(&clazz, 0);
  assert(obj);
  assert(pn_hashcode(obj) == (uintptr_t) obj);
  assert(pn_hashcode(NULL) == 0);
  pn_free(obj);
}

Example #2

File: object.c Project: MZDN/qpid-proton

static void test_stringn(const char *value, size_t size)
{
  pn_string_t *strn = pn_stringn(value, size);
