This paper briefly describes a simple example of system call time based on VC++, here only listed the main part of the code, for your reference, as follows:
The first thing to notice is to add a header file:
#include <Windows.h>
Then it will be simple, here only stick out the main usage as follows:
#ifdef _SECURITY
SYSTEMTIME sysTime;
ZeroMemory(&sysTime, sizeof(sysTime));
GetLocalTime(&sysTime);
if (sysTime.wYear > _DURE_DATE_YEAR)
exit(0);
else if (sysTime.wYear == _DURE_DATE_YEAR && sysTime.wMonth > _DURE_DATE_MONTH)
exit(0);
else if (sysTime.wYear == _DURE_DATE_YEAR && sysTime.wMonth == _DURE_DATE_MONTH && sysTime.wDay >= _DURE_DATE_DAY)
exit(0);
#endif // _SECURITY
