Greetings,
I want to send a userdefined structure over a network, I would like to know if there is a way to convert a structure into string.
LANG - C++; COMPILER - g++;
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.
