Function Documentation

signal_block()

auto zxfoundation::dgp::signal::signal_block ( domain & d, u32 mask )->void

exportnoexcept

Update the per-domain blocked mask.

Update the per-domaindomain blocked mask.

signal_deliver_all()

auto zxfoundation::dgp::signal::signal_deliver_all ( domain & d ) ->bool

exportnoexcept

Deliver all pending signals to the domain.

Deliver all pending signals to the domain::domain.

Returns

true if the domain should be rescheduled (terminate default was taken).

true if the domain::domain should be rescheduled (terminate default was taken).

signal_deliver_one()

auto zxfoundation::dgp::signal::signal_deliver_one ( domain & d ) ->bool

exportnoexcept

Deliver one unblocked pending signal to the domain.

Deliver one unblocked pending signal to the domain::domain.

Returns

True if a signal was delivered; false if the queue was empty or every pending kind was blocked.

signal_enqueue()

auto zxfoundation::dgp::signal::signal_enqueue ( domain & d, signal_kind kind, u64 data )->void

exportnoexcept

Queue a signal for asynchronous delivery to a domain.

Queue a signal for asynchronous delivery to a domain::domain.

Parameters

[in,out]	d	The target domain.
[in]	kind	Signal kind.
[in]	data	Opaque payload.
[in,out]	d	The target domain::domain.
[in]	kind	Signal kind.
[in]	data	Opaque payload.

signal_register_handler()

auto zxfoundation::dgp::signal::signal_register_handler ( domain & d, signal_kind kind, const signal_handler_info & info )->std::expected< void, lib::kernel_error >

nodiscardexportnoexcept

Register a signal handler for the given domain and kind.

Register a signal handler for the given domain::domain and kind.

Parameters

[in,out]	d	The target domain.
[in]	kind	The signal kind to handle.
[in]	info	Handler descriptor (function, user data, default).

Returns

Success, or kernel_error if kind is out of range.

Parameters

[in,out]	d	The target domain::domain.
[in]	kind	The signal kind to handle.
[in]	info	Handler descriptor (function, user data, default).

Returns

Success, or kernel_error if kind is out of range.
