Does Boost have method to do endian swap, like those ntohl and htonl?
Beman Dawes was working on an elegant endian-handling library, but
iirc it ran into problems that were only nicely fixable with C++0x
features.
In the mean time, you could implement an endian swap something like this:
#include
#include
#include
#include <algorithm>
template <typename T>
T reverse_bytes(T const x) {
BOOST_MPL_ASSERT((boost::is_integral<T>));
T y = x;
std::reverse((char*)(&y), (char*)(1+&y));
return y;
}
#if defined(BOOST_LITTLE_ENDIAN)
template <typename T>
T hton(T const x) { return reverse_bytes(x); }
template <typename T>
T ntoh(T const x) { return reverse_bytes(x); }
#else
template <typename T>
T hton(T const x) { return x; }
template <typename T>
T ntoh(T const x) { return x; }
#endif
And overload reverse_bytes for anything else you want it to work on.
