Template Function pn532::checksum

• Defined in File checksum.hpp

Function Documentation

template<class ByteIterator>
bool pn532::checksum(ByteIterator begin, ByteIterator end)

Checks that the given sequence of bytes sums up to zero. When the checksum byte (computed e.g. with compute_checksum) is appended to a sequence, the whole sequence sums up to zero. This function thus expects the sequence to end with the checksum byte.

Template Parameters:

ByteIterator – Any forward iterator type that yields std::uint8_t.

Parameters:

• begin – Iterator pointing to the first element.

• end – Past-the-end iterator.

Returns:

True if and only if the sequence sums to zero.
