This requires two pairs of messages (request and response) following receipt of theM_IOCTLmessage: the firstcopyin(9F)s the structure (address) and the secondcopyin(9F)the buffer (address.ad.addr). Two states are maintained and processed in this example:GETSTRUCTis for copying in the address...
The reference implementation of the Linux FUSE (Filesystem in Userspace) interface - libfuse/example/ioctl.c at 5aaec929a4e4fe1f3113e4dc6a1469090511207b · libfuse/libfuse
be sent by the Volume Shadow Copy Driver (volsnap.sys) during a hibernation request or before a crash dump. This IOCTL is sent to file system filter drivers, file system drivers, and other device drivers (storage filter drivers and storage drivers, for example) located below the file systems...
For example, argp = (125<<16) + 0x637 would specify the beep normally associated with a ctrl-G. (Thus since Linux 0.99pl1; broken in Linux 2.1.49-50.) KIOCSOUND Start or stop sound generation. The lower 16 bits of argp specify the period in clock cycles (that is, argp = 1193180...
The name-based operation that resulted in the prefix resolution is routed to the provider that claims the prefix. If successful, MUP ensures that subsequent handle-based operations (IRP_MJ_READ and IRP_MJ_WRITE, for example) go to the same provider completely bypassing MUP. ...

If the output does not reflect a valid terminal type, you can set it manually. For example, if you are using an xterm or a similar terminal, you can set it using: exportTERM=xterm Output: # no output expected By setting the terminal type correctly, you increase the chances of resolving...
