read_blob()

std::vector< uint8_t > MayaFlux::Transitive::Protocol::read_blob ( const uint8_t *  data, size_t  max_len, size_t &  offset  )

inline

Read a length-prefixed blob from a byte buffer.

Format: [int32 size (big-endian)][data, padded to 4-byte boundary]. Advances offset past the blob. Returns empty vector on invalid size.

Parameters

data	Buffer start.
max_len	Total buffer size in bytes.
offset	Current read position, advanced on return.

Definition at line 99 of file BinaryBuffer.hpp.

    int32_t blob_size = read_int32(data, offset);

        || offset + static_cast<size_t>(blob_size) > max_len) {
        return {};
    }
    std::vector<uint8_t> result(
        data + offset, data + offset + blob_size);
    offset += padded_size(static_cast<size_t>(blob_size));
    return result;
