Struct ipc64_perm_t

#[repr(C)]
pub struct ipc64_perm_t {
    pub key: i32,
    pub uid: u32,
    pub gid: u32,
    pub cuid: u32,
    pub cgid: u32,
    pub mode: u32,
    pub seq: u16,
    /* private fields */
}

Available on crate feature dep_nc only.

The generic ipc64_perm structure: Note extra padding because this structure is passed back and forth between kernel and user space.

ipc64_perm was originally meant to be architecture specific, but everyone just ended up making identical copies without specific optimizations, so we may just as well all use the same one.

Pad space is left for:

• 32-bit mode_t on architectures that only had 16 bit
• 32-bit seq
• 2 miscellaneous 32-bit values

Fields

key: i32

uid: u32

gid: u32

cuid: u32

cgid: u32

mode: u32

pad if mode_t is u16:

seq: u16
