My client maps NT_STATUS_DISK_FULL to EFBIG, but really this should be done
by observing some Windows server. With W2K/NTFS I had no success - using
SMB_SET_FILE_END_OF_FILE_INFO doesn't generate a sparse file so I fill up
the disk before hitting any filesize limit. Maybe setting
FILE_ATTRIBUTE_SPARSE would do it. Another approach... is there a
Windoze/filesystem combo with a filesize limit of 4G or less? That would
make this easy.
