Constructors

ChildWatchSource (GPid pid)
Constructs a new child watch source.
ChildWatchSource (GPid pid, const WatchSlot &slot)
Constructs a new child watch source.

Methods

sigc::connection connect (const WatchSlot &slot)
Connects the callback slot to the child watch source.

Detailed Description

A child watch GSource C++ interface.

A slot connected to a ChildWatchSource is called when the child indicated by pid exits, at a default priority, G_PRIORITY_DEFAULT.

Constructor & Destructor Documentation

Xfc::G::ChildWatchSource::ChildWatchSource ( GPid pid )

Constructs a new child watch source.

Parameters:

pid The process id of a child process to watch.

The source will not initially be associated with any main context and must be added to one with G::Source::attach() before it will be executed. Note that on platforms where GPid must be explicitely closed pid must not be closed while the source is still active (see G::Spawn::close_pid()). Typically, you will want to call G::Spawn::close_pid() in the callback slot method for the source.
To set the callback slot call set_callback(). To override the default priority PRIORITY_DEFAULT call set_priority().

Xfc::G::ChildWatchSource::ChildWatchSource ( GPid pid,

const WatchSlot & slot

)

Constructs a new child watch source.

Parameters:

pid The process id of a child process to watch.

slot The child watch callback slot, of type sigc::slot<void, GPid, int>.

The source will not initially be associated with any main context and must be added to one with G::Source::attach() before it will be executed. Note that on platforms where GPid must be explicitely closed pid must not be closed while the source is still active (see G::Spawn::close_pid()). Typically, you will want to call G::Spawn::close_pid() in the callback slot method for the source.
