KProcessController

protected KProcessController(Class dummy)

Method Detail

addKProcess

public void addKProcess(KProcess arg1)

UNKNOWN:

deref

public static void deref()

Destroy the instance if one exists and it is not referenced any more. Called by KApplication.~KApplication()

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

ref

public static void ref()

Create an instance if none exists yet. Called by KApplication.KApplication()

UNKNOWN: Create an instance if none exists yet.

removeKProcess

public void removeKProcess(KProcess arg1)

UNKNOWN:

rescheduleCheck

public void rescheduleCheck()

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

UNKNOWN: This function @em must be called at some point after calling unscheduleCheck().

theSigCHLDHandler

public static void theSigCHLDHandler(int signal)

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().

UNKNOWN: Automatically called upon SIGCHLD.

unscheduleCheck

public void unscheduleCheck()

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

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

waitForProcessExit

public boolean 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: timeout the timeout in seconds. -1 means no timeout.

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

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