Is sys/time.h a windows header? I'm trying to compile code and it says that the header is missing. Where can I download sys/time.h?

Thank you once again Albert...will research now. This is the code.

#ifdef WIN32
#include <sys time.h="">
#include <time.h>

#include "pcap.h"
#include "pcap/bpf.h
#include <stdio.h>

int main()
pcap_if_t *alldevs;
pcap_if_t *d;
int i=0;
char errbuf[PCAP_ERRBUF_SIZE];

/* Retrieve the device list from the local machine */
if (pcap_findalldevs_ex(PCAP_SRC_IF_STRING, NULL, &alldevs, errbuf) == -1)
cout << "Error in pcap_findalldevs_ex: %s\n";
return 0;

/* Print the list */
for(d= alldevs; d != NULL; d= d->next)
printf("%d. %s", ++i, d->name);
if (d->description)
printf(" (%s)\n", d->description);
printf(" (No description available)\n");

if (i == 0)
printf("\nNo interfaces found! Make sure WinPcap is installed.\n");
return 0;

/* We don't need any more the device list. Free it */

return 0;

don't see where any of this calls anything relating to time, maybe one of your headers is using it?

I'll check pcap.h it might be there. What is this sys/ that I'm reading about, is this windows?

Found it, it is in pcap.h

#if defined(WIN32)
#include <pcap-stdinc.h>
#elif defined(MSDOS)
#include <sys types.h="">
#include <sys socket.h=""> /* u_int, u_char etc. */
#else /* UN*X */
#include <sys types.h="">
#include <sys time.h="">
#endif /* WIN32/MSDOS/UN*X */

How can I rem it out?

I still don't see where there's a call to "sys/time.h" regardless, make sure you have "#define WIN32" somewhere before you include pcap.h, that should tell it to use standard includes instead of unix
