[nasim751]

how you will deal this problem and what should be the correct syntax............

Convert time from pcap pkthdr format (double longs) to 
1/10,000 seconds since midnight
*/
int get_pkttime (struct pcap_pkthdr *pkthdr)
 {
	struct tm *time;
	time = localtime(&pkthdr->ts.tv_sec);
	return  
		(int)
		pkthdr->ts.tv_usec/100 +  /*  Convert microseconds */
		M0SEC *(time->tm_sec + 60*(time->tm_min + 60*time->tm_hour));
}

You cannot use types that has not been declared or defined. The compiler must see an appropriate declaration or definition before it can use said type.
This error is usually because you forget to include a proper header file.
