Does boost have portable way to use ntohl/htonl/nt

Question

I am using UDP in particular boost::asio::ip::udp::socket sockets if that helps?

What is the header file?

What headers/classes do I need to handle network byte ordering with the UDP under boost?

For Windows:

For *nix:

A quick search did not provide anything resonable in boost.
Hopefuuly somebody else will find somthing.

Answer 2

Just found it is enough to #include <boost/asio.hpp> as this pulls in all the platform dependent headers and gives access to htonl/ntohl which is exactly what I need.

Thanks all for the suggestions.

Answer 3

boost::asio::detail::socket_ops::host_to_network_short in boost/asio/detail/socket_ops.hpp

Answer 4

POSIX.1-2001 standard is <sys/types.h> & <netinet/in.h>, on Windows you have 2 stacks to choose from <winsock2.h> or <ws2tcpip.h> & <winsock2.h>, the latter is now the preferred choice as it supports Unicode naming but note that they are incompatible.

Platforms pre-2001 might require other headers such as <arpa/inet.h>.
