C++ (Cpp) Error::Set Examples

Example #1

File: GRecord.cpp Project: kwtskran/XCSoar

bool
GRecord::VerifyGRecordInFile(Path path, Error &error)
{
  // assumes FileName member is set
  // Load File into Buffer (assume name is already set)
  if (!LoadFileToBuffer(path, error))
    return false;

  // load Existing Digest "old"
  char old_g_record[DIGEST_LENGTH + 1];
  if (!ReadGRecordFromFile(path, old_g_record, ARRAY_SIZE(old_g_record), error))
    return false;

  // recalculate digest from buffer
  FinalizeBuffer();

  char new_g_record[DIGEST_LENGTH + 1];
  GetDigest(new_g_record);

  if (strcmp(old_g_record, new_g_record) != 0) {
    error.Set(grecord_domain, "Invalid G record");
    return false;
  }

  return true;
}

Example #2

File: GRecord.cpp Project: kwtskran/XCSoar

bool
GRecord::ReadGRecordFromFile(Path path,
                             char *output, size_t max_length,
                             Error &error)

    return false;

  unsigned int digest_length = 0;
  char *data;
  while ((data = reader.ReadLine()) != nullptr) {
