C++ (Cpp) BinaryStreamWriter::writeArray Examples

Example #1

File: PDBStringTableBuilder.cpp Project: CTSRD-CHERI/cheribsd

Error PDBStringTableBuilder::writeHashTable(BinaryStreamWriter &Writer) const {
  // Write a hash table.
  uint32_t BucketCount = computeBucketCount(Strings.size());
  if (auto EC = Writer.writeInteger(BucketCount))
    return EC;
  std::vector<ulittle32_t> Buckets(BucketCount);

  for (auto &Pair : Strings) {
    StringRef S = Pair.getKey();
    uint32_t Offset = Pair.getValue();
    uint32_t Hash = hashStringV1(S);

    for (uint32_t I = 0; I != BucketCount; ++I) {
      uint32_t Slot = (Hash + I) % BucketCount;
      if (Buckets[Slot] != 0)
        continue;
      Buckets[Slot] = Offset;
      break;
    }
  }

  if (auto EC = Writer.writeArray(ArrayRef<ulittle32_t>(Buckets)))
    return EC;

  assert(Writer.bytesRemaining() == 0);
  return Error::success();
}

Example #2

  GSIHashHeader Header;
  Header.VerSignature = GSIHashHeader::HdrSignature;
  Header.VerHdr = GSIHashHeader::HdrVersion;
  Header.HrSize = HashRecords.size() * sizeof(PSHashRecord);
  Header.NumBuckets = HashBitmap.size() * 4 + HashBuckets.size() * 4;

  if (auto EC = Writer.writeObject(Header))
    return EC;

  if (auto EC = Writer.writeArray(makeArrayRef(HashRecords)))
    return EC;

}
