Member Function Documentation

deref()

void TDEProcessController::deref ( )

static

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

Called by TDEApplication::~TDEApplication()

Definition at line 48 of file kprocctrl.cpp.

ref()

void TDEProcessController::ref ( )

static

Create an instance if none exists yet.

Called by TDEApplication::TDEApplication()

Definition at line 39 of file kprocctrl.cpp.

rescheduleCheck()

void TDEProcessController::rescheduleCheck

(

)

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

Definition at line 178 of file kprocctrl.cpp.

theSigCHLDHandler()

void TDEProcessController::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 147 of file kprocctrl.cpp.

unscheduleCheck()

void TDEProcessController::unscheduleCheck

(

)

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

(

int

timeout

)

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