Detailed Description

Encapsulates KPty into a QIODevice, so it can be used with Q*Stream, etc.

Definition at line 20 of file kptydevice.h.

Constructor & Destructor Documentation

KPtyDevice()

KPtyDevice::KPtyDevice ( QObject * parent = nullptr )

explicit

Constructor.

Definition at line 448 of file kptydevice.cpp.

~KPtyDevice()

KPtyDevice::~KPtyDevice ( )

override

Destructor:

If the pty is still open, it will be closed. Note, however, that an utmp registration is not undone.

close()

void KPtyDevice::close ( )

overridevirtual

Close the pty master/slave pair.

Reimplemented from QIODevice.

Definition at line 491 of file kptydevice.cpp.

isSequential()

bool KPtyDevice::isSequential ( ) const

overridevirtual

Returns

always true

Reimplemented from QIODevice.

Definition at line 507 of file kptydevice.cpp.

isSuspended()

bool KPtyDevice::isSuspended

(

)

const

Returns true if the KPtyDevice is not monitoring the pty for incoming data.

Do not use on closed ptys.

See setSuspended()

Definition at line 554 of file kptydevice.cpp.

open() [1/2]

bool KPtyDevice::open	(	int	fd,
		OpenMode	mode = ReadWrite | Unbuffered )

Open using an existing pty master.

The ownership of the fd remains with the caller, i.e., close() will not close the fd.

This is useful if you wish to attach a secondary "controller" to an existing pty device such as a terminal widget. Note that you will need to use setSuspended() on both devices to control which one gets the incoming data from the pty.

Parameters

fd	an open pty master file descriptor.
mode	the device mode to open the pty with.

Returns

true if a pty pair was successfully opened

Definition at line 477 of file kptydevice.cpp.

open() [2/2]

bool KPtyDevice::open ( OpenMode mode = ReadWrite | Unbuffered )

overridevirtual

Create a pty master/slave pair.

Returns

true if a pty pair was successfully opened

Reimplemented from QIODevice.

Definition at line 459 of file kptydevice.cpp.

readData()

qint64 KPtyDevice::readData ( char * data, qint64 maxSize )

overrideprotectedvirtual

Implements QIODevice.

Definition at line 561 of file kptydevice.cpp.

readEof

void KPtyDevice::readEof ( )

signal

Emitted when EOF is read from the PTY.

Data may still remain in the buffers.

readLineData()

qint64 KPtyDevice::readLineData ( char * data, qint64 maxSize )

overrideprotectedvirtual

Reimplemented from QIODevice.

Definition at line 568 of file kptydevice.cpp.

setSuspended()

void KPtyDevice::setSuspended

(

bool

suspended

)

Sets whether the KPtyDevice monitors the pty for incoming data.

When the KPtyDevice is suspended, it will no longer attempt to buffer data that becomes available from the pty and it will not emit any signals.

Do not use on closed ptys. After a call to open(), the pty is not suspended. If you need to ensure that no data is read, call this function before the main loop is entered again (i.e., immediately after opening the pty).

Definition at line 548 of file kptydevice.cpp.

waitForBytesWritten()

bool KPtyDevice::waitForBytesWritten ( int msecs = -1 )

overridevirtual

Reimplemented from QIODevice.

Definition at line 542 of file kptydevice.cpp.

waitForReadyRead()

bool KPtyDevice::waitForReadyRead ( int msecs = -1 )

overridevirtual

Reimplemented from QIODevice.

Definition at line 536 of file kptydevice.cpp.

writeData()

qint64 KPtyDevice::writeData ( const char * data, qint64 maxSize )

overrideprotectedvirtual

Implements QIODevice.
