Detailed Description

Used internally by KProcess.

Definition at line 39 of file kprocctrl.h.

Member Function Documentation

void KProcessController::deref ( )
static

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

Called by KApplication::~KApplication()

Definition at line 48 of file kprocctrl.cpp.

void KProcessController::ref ( )
static

Create an instance if none exists yet.

Called by KApplication::KApplication()

Definition at line 39 of file kprocctrl.cpp.

void KProcessController::rescheduleCheck ( )

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

Since
3.2

Definition at line 178 of file kprocctrl.cpp.

void KProcessController::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.

void KProcessController::unscheduleCheck ( )

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

Since
3.2

Definition at line 170 of file kprocctrl.cpp.

bool KProcessController::waitForProcessExit ( int  timeout)

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

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

Parameters
timeoutthe timeout in seconds. -1 means no timeout.
Returns
true if a process exited, false if no process exited within timeout seconds.
Since
3.1

Definition at line 223 of file kprocctrl.cpp.
