Struct SignalStackFrame 

pub struct SignalStackFrame {
    pub siginfo_bytes: [u8; 128],
    pub context: ucontext,
    /* private fields */
}

A SignalStackFrame contains all the state that is stored on the stack prior to executing a signal handler.

The ordering of the fields is significant, as it is part of the syscall ABI. In particular, restorer_address must be the first field, since that is where the signal handler will return after it finishes executing.

Fields

siginfo_bytes: [u8; 128]

Information about the signal.

context: ucontext

The state of the thread at the time the signal was handled.

Implementations

impl SignalStackFrame

pub fn new( _task: &Task, arch_width: ArchWidth, registers: &RegisterState, extended_pstate: &ExtendedPstateState, signal_state: &SignalState, siginfo: &SignalInfo, action: sigaction_t, stack_pointer: UserAddress, ) -> Result<SignalStackFrame, Errno>

pub fn as_bytes(&self) -> &[u8; 1280]

pub fn from_bytes(bytes: [u8; 1280]) -> SignalStackFrame

pub fn get_signal_mask(&self) -> SigSet
