Struct linux_api::signal::sigaction

source ·
#[repr(C)]
pub struct sigaction(/* private fields */);
Expand description

§Invariants

sigaction does not require or guarantee that its internal function pointers, if any, are safe to call/dereference.

Implementations§

source§

impl sigaction

source

pub fn new_raw( handler: SignalHandler, flags: SigActionFlags, mask: sigset_t, restorer: Option<unsafe extern "C" fn()>, ) -> Self

Consider sigaction::new_with_default_restorer instead, which takes care of setting up a restorer.

panics if handler is inconsistent with the presence or absence of the SA_SIGINFO flag.

source

pub fn new_with_default_restorer( handler: SignalHandler, flags: SigActionFlags, mask: sigset_t, ) -> Self

Creates a sigaction with SA_RESTORER set, and the internal restorer field set to sigaction_restorer. The libc sigaction function normally makes these changes to the provided struct sigaction.

source

pub fn wrap(si: linux_sigaction) -> Self

source

pub fn wrap_ref(si: &linux_sigaction) -> &Self

source

pub fn wrap_mut(si: &mut linux_sigaction) -> &mut Self

source

pub unsafe fn peel(si: Self) -> linux_sigaction

§Safety

lsa_handler is safe to dereference iff the lsa_handler used to construct Self is.

source

pub fn flags(&self) -> Option<SigActionFlags>

source

pub fn flags_retain(&self) -> SigActionFlags

source

pub fn mask(&self) -> sigset_t

source

pub unsafe fn handler(&self) -> SignalHandler

§Safety

The functions in SignalHandler::Action or SignalHandler::Handler are safe to call iff the function pointer in the internal lsa_handler is, and is of the type specified in the internal lsa_flags.

source

pub fn is_ignore(&self) -> bool

source

pub fn is_default(&self) -> bool
