[Original] time function implementation in WindowsCE

When we create an application today,ProgramWe need to generate a random number and use time (0) to set the starting point of the random number. We found that wince has time. h: This header file, but it prompts that the time function is an unrecognizable symbol. Google, we found that there was no time function implementation in Lib, so...

Provides a time simulation function.CodeAs follows:

Time_t mytime (time_t * Intt)
{
Systemtime using imestruct;
Filetime ftime;
Ularge_integer int64time;
Time_t loctt =   0 ;

If (intt = null)
intt = & loctt;

Getsystemtime (&Systimestruct );

If (Systemtimetofiletime ( & Systimestruct, & Ftime ))
{
Memcpy ( & Int64time, & Ftime, Sizeof (Filetime ));
/* Subtract the value for (UTC) */
Int64time. quadpart -=   0x19db1ded53e8000 ;
/* Convert to seconds. */
Int64time. quadpart /=   10000000 ;
* Intt = Int64time. quadpart;
}
Return   * Intt;
}
