C++ (Cpp) CreateSlice Examples

Example #1

File: nsDOMFile.cpp Project: CodeSpeaker/gecko-dev

nsresult
DOMFileImpl::Slice(int64_t aStart, int64_t aEnd,
                   const nsAString& aContentType, uint8_t aArgc,
                   nsIDOMBlob **aBlob)
{
  *aBlob = nullptr;

  // Truncate aStart and aEnd so that we stay within this file.
  uint64_t thisLength;
  nsresult rv = GetSize(&thisLength);
  NS_ENSURE_SUCCESS(rv, rv);

  if (aArgc < 2) {
    aEnd = (int64_t)thisLength;
  }

  ParseSize((int64_t)thisLength, aStart, aEnd);

  // Create the new file
  nsCOMPtr<nsIDOMBlob> blob =
    CreateSlice((uint64_t)aStart, (uint64_t)(aEnd - aStart), aContentType);

  blob.forget(aBlob);
  return *aBlob ? NS_OK : NS_ERROR_UNEXPECTED;
}

Example #2

{
  *aBlobImpl = nullptr;

  // Truncate aStart and aEnd so that we stay within this file.
