_get_osfhandle
Visual Studio 2008
Returns operating-system file handle associated with existing low-level file descriptor.
long _get_osfhandle( int fd );
The _get_osfhandle function returns an operating-system file handle if fd (the low-level file descriptor) is in range and is internally marked as free. Otherwise, the invalid parameter handler is invoked, as described in Parameter Validation. If execution is allowed to continue, this function returns INVALID_HANDLE_VALUE (–1) and sets errno to EBADF, indicating an invalid file handle.
