[zeromq-dev] zhelpers.hpp can not be compiled under Windows

[Oleg Vazhnev]

Hi

I'm trying to run pub-sub example on Windows.
I've run succesfully wuserver / wuclient example, but by some reason it 
doesn't work (i just do not receive items).

So I've decided to try syncpub / syncsub example, but they require 
zhelpers.hpp file: 
https://github.com/imatix/zguide/blob/master/examples/C%2B%2B/zhelpers.hpp


It seems this file is kind of ready to be run under Windows, most part 
of the system calls are surrounded with #ifdef, like this one:

#if (defined (__WINDOWS__))
     SYSTEMTIME st;
     GetSystemTime (&st);
     return (int64_t) st.wSecond * 1000 + st.wMilliseconds;
#else
     struct timeval tv;
     gettimeofday (&tv, NULL);
     return (int64_t) (tv.tv_sec * 1000 + tv.tv_usec / 1000);
#endif

However I still have several compile errors on these lines:

#include <sys/time.h>
#include <unistd.h>
#include <pthread.h>

static void s_catch_signals ()
{
     struct sigaction action;

Also this macro should be changed:

#define within(num) (int) ((float) (num) * random () / (RAND_MAX + 1.0))

Because under Windows "random" should be "rand"

==============================================================

I've commented "s_catch_signals" function and corresonding includes, 
fixed macro (random => rand) and code compiles.

So it seems while entire file is platform-independent, "s_catch_signals" 
function is Linux-only. I guess probably it's better to move it to 
another place. Then examples will compile under Windows.


Thanks,
  Oleg
