For speed reason, you can use GetSystemTimeAsFileTime(), which is
very efficient. The Win32 is little-endian only operating system.
You can use the following code.
void gettimeofday(struct timeval* pTv, void *pDummy);
{
__int64 l;
GetSystemTimeAsFileTime((LPFILETIME) &l);
pTv->tv_sec = (long) l / 10000000; /*10e7*/
pTv->tv_usec = (unsigned long) (i.QuadPart / 10) % 1000000; /*10e6*/
}
You missed the cast.
