Question

Tried to find a complete analog to the function SystemTimeToFileTime, but cannot find it.

I have all the SYSTEMTIME and FILETIME structures with correctly working SYSTEMTIME on linux for the date difference function:

int64_t Delta2(const SYSTEMTIME st1, const SYSTEMTIME st2) { 

    union timeunion { FILETIME fileTime; ULARGE_INTEGER ul; } ;
    timeunion ft1;
    timeunion ft2;
    SystemTimeToFileTime(&st1, &ft1.fileTime);
    SystemTimeToFileTime(&st2, &ft2.fileTime);

    return ft2.ul.QuadPart - ft1.ul.QuadPart; 
}

Anybody knows an exact replacement of the SystemTimeToFileTime function?

I suggest you consult the sources of the WINE project which will contain exactly what you need.
