Greetings,

There is no need to convert a structure into a string. Trust the C library to make it easy for you.

The following is an elegant solution

Here is a code snippet for you

#include <sys/uio.h>

// define a structure of type iovec iovec iov[0];

// rtt_hdr is my header structure // for RTT packet. Pass the base address // and the size of the header

iov[0].iov_base = &rtt_hdr; iov[0].iov_len = sizeof(rtt_hdr);

then use the readv/writev calls to read and write to the network socket.

refer pg 357-358 of Unix Network programming - Richard Stevens Volume 1 ( I am not qouting this from memory - just that I located the book nearby ;)

Also refer the manpages of readv / writev C library calls.
