"Const long * _ w64" is converted to "const time_t *" during Winpcap transplantation.

The error occurs in the following sentence:

Struct TM * ltime;
Char timestr [16];
Ltime = localtime (& header-> TS. TV _sec );

Error message:

Error c2664: "localtime": the parameter 1 cannot be converted from "const long * _ w64" to "const time_t *"

Analysis:

In vc6.0, time_t is defined:
Typedef long time_t;
It is actually long, so it can be used universally.

But in vs2005, it is different:
How to define _ use_32bit_time_t?
Typedef _ time64_t time_t;
Typedef _ int64 _ time64_t;
That is to say, time_t is a 64-bit integer.

Add _ use_32bit_time_t to the "pre-processing definition" in 'C/C ++ 'of the Project attribute to directly use long time.

Of course, we 'd better take yourCodeChanged:
Struct TM * date_tm;
Time_t time;

Time (& time );
Date_tm = localtime (& time );

In this way, you can use it.
