Module base::sys::unix::signal

Macros

ok_if 🔒

Treat some errno’s as Ok(()).

Structs

BlockedSignal

KillOnDrop

Wraps a Child process, and calls kill_tree for its process group to clean it up when dropped.

Enums

Error

Signal

Constants

DEFAULT_KILL_TIMEOUT 🔒

POLL_RATE 🔒

Traits

Killable

Trait for threads that can be signalled via pthread_kill.

Functions

SIGRTMAX

Returns the maximum (inclusive) real-time signal number.

SIGRTMIN

Returns the minimum (inclusive) real-time signal number.

__libc_current_sigrtmax 🔒 ^⚠

__libc_current_sigrtmin 🔒 ^⚠

block_signal

Masks given signal.

clear_signal

Clears pending signal.

clear_signal_handler

Resets the signal handler of signum num back to the default.

create_sigset

Creates sigset from an array of signal numbers.

get_blocked_signals

Retrieves the signal mask of the current thread as a vector of c_ints.

has_default_signal_handler

Returns true if the signal handler for signum num is the default.

kill^⚠

Safety

kill_tree

Terminates and reaps a child process. If the child process is a group leader, its children will be terminated and reaped as well. After the given timeout, the child process and any relevant children are killed (i.e. sent SIGKILL).

register_rt_signal_handler^⚠

Registers handler as the signal handler for the real-time signal with signum num.

register_signal_handler^⚠

Registers handler as the signal handler of signum num.

unblock_signal

Unmasks given signal.

valid_rt_signal_num 🔒

wait_for_signal

Wait for signal before continuing. The signal number of the consumed signal is returned on success. EAGAIN means the timeout was reached.
