coreyoconnor / boost_array_hex_dump.cpp
Created November 13, 2008 22:11
A quick hack to make a hex dumper for boost::arrays
template<typename array_type, std::size_t array_size>
std::string hex_dump_array(const boost::array<array_type, array_size>& in_array)
{
// 100 chars max stride. 2 chars per byte.
using namespace std;
const uint32_t chunks_per_stride = 50 / (sizeof(array_type) + 1);
uint32_t chunk_offset = 0;
std::stringstream out_stream;
std::string stride_txt;
