Struct OpenReply 

#[repr(C, packed(1))]
pub struct OpenReply {
    pub status: u32,
    pub file_id: u64,
    pub size: u64,
    pub file_flags: u32,
}

Open reply.

Wire layout: status @ 0..4, file_id @ 4..12, size @ 12..20, file_flags @ 20..24.

Wire-compatibility note

Earlier documentation wrongly claimed _pad0 @ 4..8, ino @ 8..16, size @ 16..24, file_flags @ 24..28 (32 bytes); no server ever produced that layout. The real layout above is what every scheme server (net, bus) emits and what the kernel VFS client parses.

Fields

status: u32

Status code: 0 = success.

file_id: u64

Handle/id of the opened file.

size: u64

File size in bytes (u64::MAX = size unknown).

file_flags: u32

File flags (device, pipe, chunked read/write, directory…).
