Objet?: [Winpcap-users] About struct timeval and header->ts.tv_usec


Hi,
struct pcap_pkthdr {
	struct timeval ts;  
	bpf_u_int32 caplen; 
	bpf_u_int32 len;    
};

1.What's the definition of "struct timeval"? I searched WinPcap's source 
file,but I didn't find.

2.How can I convert header->ts.tv_usec to readable format?

Thanks

Zhiyu He
