Does boost have portable way to use ntohl/htonl/ntohs/htons type functions?

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?

Answer 1

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 2

在boost / asio / detail / socket_ops.hpp中的boost :: asio :: detail :: socket_ops :: host_to_network_short

Answer 3

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> .

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