SIOCOUTQ: wrong value type?

[konnextv]

I just discovered this crate today while researching ioctls and am a beginner when it comes to these kind of 'kernel' calls.

From the docs that I found SIOCOUTQ should output an integer (32-bit) but this crates generated function wants a *mut u8

Please enlighten me or excuse me if I am not understanding this correctly!

Likely a bug. Ideally it would accept a *mut u32. In practice, it's an unsafe wrapper accepting a pointer, so folks can cast around and get things working.

Even more ideally, we'd have something generating functions that accept references instead of pointers for those ioctls where it's sensible.

I'd accept a PR to fix this, but I'm not actively maintaining this, and you may find it better to place good ioctl wrappers for the functionality you desire into its own crate which abstracts the functionality you desire in a usable way.
