But there is no guarantee that disk_size/block_size < INT_MAX.. May be, additional option, specifying the shift would be better. With convention that if offset+length exceeds disk size, length should be recalculated as disk_size-offset. -- Best regards, Vladimir ------------------------------------------------------------------------------ _______________________________________________ Nbd-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/nbd-general
