pod Windows próbuję:
void truncate(char *path, uint64_t position)
{
LARGE_INTEGER lr;
lr.QuadPart = position;
OFSTRUCT ofstruct;
HANDLE hFile = OpenFile(path, &ofstruct, OF_WRITE);
SetFilePointer(hFile, lr.LowPart, &lr.HighPart, FILE_BEGIN);
SetEndOfFile(hFile);
CloseHandle(hFile);
}
Ale błąd bo OpenFile() chce podawać HFILE a nie HANDLE, natomiast
pozostałe funkcje chcą HANDLE.
