Struct syscall::io_uring::v1::CqEntry32

#[repr(C, align(16))]pub struct CqEntry32 {
    pub user_data: u32,
    pub status: u32,
    pub flags: u32,
    pub extra: u32,
}

A 32-bit Completion Queue Entry. Takes up 16 bytes of space.

Fields

user_data: u32

The same user_data specified in the submission entry.

status: u32

The return value of the syscall.

flags: u32

Miscellaneous flags (and possibly other data in the future) describing the completion in general.

extra: u32

An extra return value that is only used by certain opcodes.
