Re: [Boost-users] Is there a something in boost to facilitate binary buffer transformations into typed data structures/classes?

Or:
memcpy(&dr, &buffer[0], buffer.size());

Or use union to avoid making a copy:

union {
  data d;
  unsigned char bytes[4];
} u;

bytes[0] = 3;
bytes[1] = 6;
bytes[2] = 0;
bytes[3] = 9;

// use d.first, d.second, d.third
