A class for internal use by K3Process only. – Exactly one instance of this class is created by KApplication.

This class takes care of the actual (UN*X) signal handling.

void K3ProcessController::addKProcess

K3Process *

p

Definition at line 316 of file k3processcontroller.cpp.

void K3ProcessController::addProcess

(

int

pid

)

Definition at line 326 of file k3processcontroller.cpp.

void K3ProcessController::deref ( )

static

Destroy the instance if one exists and it is not referenced any more.

Called by KApplication::~KApplication()

Definition at line 73 of file k3processcontroller.cpp.

K3ProcessController * K3ProcessController::instance ( )

static

Only a single instance of this class is allowed at a time.

This method provides access to that instance.

Definition at line 83 of file k3processcontroller.cpp.

int K3ProcessController::notifierFd

(

)

const

Definition at line 220 of file k3processcontroller.cpp.

void K3ProcessController::ref ( )

static

Create an instance if none exists yet.

Called by KApplication::KApplication()

Definition at line 64 of file k3processcontroller.cpp.

void K3ProcessController::removeKProcess

(

K3Process *

p

)

Definition at line 321 of file k3processcontroller.cpp.

void K3ProcessController::rescheduleCheck

(

)

This function must be called at some point after calling unscheduleCheck().

Definition at line 233 of file k3processcontroller.cpp.

void K3ProcessController::theSigCHLDHandler ( int  signal )

static

Automatically called upon SIGCHLD.

Never call it directly. If your application (or some library it uses) redirects SIGCHLD, the new signal handler (and only it) should call the old handler returned by sigaction().

Definition at line 201 of file k3processcontroller.cpp.

void K3ProcessController::unscheduleCheck

(

)

Call this function to defer processing of the data that became available on notifierFd().

Definition at line 225 of file k3processcontroller.cpp.

bool K3ProcessController::waitForProcessExit

(

int

timeout

)

Wait for any process to exit and handle their exit without starting an event loop.

This function may cause K3Process to emit any of its signals.

Parameters

timeout

the timeout in seconds. -1 means no timeout.

Returns

true if a process exited, false if no process exited within timeout seconds.
