8.8.1.24: MTCOMPRESSION

C code
struct mtop op = { MTCOMPRESSION, COUNT };
result = ioctl(tapefd, MTIOCTOP, &op);

Description

With ftape-3.04d it can be used to enable compression when using the `/dev/qft*' and `/dev/nqft*' devices which normally wouldn't use compression.


Pitfalls

This command is no longer supported with ftape-4.05.


Example

enable compression for `/dev/qft0'

mt -f /dev/nqft0 compress 1

Example

disable compression for `/dev/qft0'

mt -f /dev/nqft0 compress 0
