Expand description

Saved thread context pushed onto the user stack during signal delivery.

This is a C-compatible structure so that the signal handler trampoline can pass a pointer to it back to sys_sigreturn. The layout must remain stable across kernel versions for ABI compatibility.

Fields§

§trampoline_ret_addr: u64

Address of the sigreturn trampoline code placed just after this struct.

§signum: u64

Signal number that caused this delivery.

§saved_mask: u64

The process signal mask at the time of delivery (restored on sigreturn).
