Struct RawAction

source
#[repr(C, align(16))]
pub struct RawAction { pub first: AtomicU64, pub user_data: AtomicU64, }

Fields§

§first: AtomicU64

Only two MSBs are interesting for the kernel. If bit 63 is set, signal is ignored. If bit 62 is set and the signal is SIGTSTP/SIGTTIN/SIGTTOU, it’s equivalent to the action of SIGSTOP.

§user_data: AtomicU64

Completely ignored by the kernel, but exists so userspace can (when 16-byte atomics exist) atomically set both the handler, sigaction flags, and sigaction mask.
