NAME
        NameFromFH -- Get the name of an open filehandle (V36)

   SYNOPSIS
        success = NameFromFH(fh, buffer, len)
        D0                   D1    D2    D3

        bool namefromfh(bptr, strptr, long)

   FUNCTION
        Returns a fully qualified path for the filehandle.  This routine is
        guaranteed not to write more than len characters into the buffer.  The
        name will be null-terminated.  See namefromlock() for more information.

        Note: Older filesystems that don't support examinefh() will cause
        NameFromFH() to fail with ERROR_ACTION_NOT_SUPPORTED.

   INPUTS
        fh     - lock of object to be examined.
        buffer - Buffer to store name.
        len    - Length of buffer.

   RESULT
        success - Success/failure indicator.
