C++ (Cpp) H_CAST_SEQ Examples

Example #1

File: rr.c Project: spease/hammer

const HParsedToken* act_cstr(const HParseResult *p) {
  dns_cstr_t *cs = H_ALLOC(dns_cstr_t);

  const HCountedArray *arr = H_CAST_SEQ(p->ast);
  uint8_t *ret = h_arena_malloc(arr->arena, sizeof(uint8_t)*arr->used);
  for (size_t i=0; i<arr->used; ++i)
    ret[i] = H_CAST_UINT(arr->elements[i]);
  assert(ret[arr->used-1] == '\0'); // XXX Is this right?! If so, shouldn't it be a validation?
  *cs = ret;

  return H_MAKE(dns_cstr_t, cs);
}

Example #2

File: application.c Project: AliBahar/dnp3

static HParsedToken *act_bytes(const HParseResult *p, void *user)
{
    DNP3_Object *o = H_ALLOC(DNP3_Object);
    HCountedArray *a = H_CAST_SEQ(p->ast);
    size_t n = a->used;

    o->applid.len = n;
    o->applid.str = h_arena_malloc(p->arena, n+1);  // null-terminate

    for(size_t i=0; i<n; i++)
        o->applid.str[i] = H_CAST_UINT(a->elements[i]);
    o->applid.str[n] = '\0';

    return H_MAKE(DNP3_Object, o);
}

Example #3

  dns_rr_txt_t *txt = H_ALLOC(dns_rr_txt_t);

  const HCountedArray *arr = H_CAST_SEQ(p->ast);
