Get HANDLE from QFile

问题

I have a QFile, but I need to call some Win32 functions on it that accept only a HANDLE. Is there a way to retrieve the underlying HANDLE of the QFile?

回答1:

I found a way that uses _get_osfhandle() (available in MinGW and VS):

QFile file;
....
HANDLE handle = (HANDLE) _get_osfhandle(file.handle()).
