Detailed Description

This class provides a way for consoles (TTYs) to be created to interact with applications.

registerConsole is called by a class that subclasses RequestQueue. getConsole returns a File that forwards any read/write requests straight to that RequestQueue backend.

read: request with p1: CONSOLE_READ, p2: param, p3: requested size, p4: buffer. write: request with p1: CONSOLE_WRITE, p2: param, p3: size of buffer, p4: buffer.

virtual bool ConsoleManager::createDirectory	(	File *	parent,
		const String &	filename,
		uint32_t	mask

inlineprotectedvirtual

createDirectory calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 404 of file Console.h.

virtual bool ConsoleManager::createFile	(	File *	parent,
		const String &	filename,
		uint32_t	mask
	)

inlineprotectedvirtual

createFile calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 399 of file Console.h.

virtual bool ConsoleManager::createSymlink	(	File *	parent,
		const String &	filename,
		const String &	value
	)

inlineprotectedvirtual

createSymlink calls this after it has parsed the string path.

Implements Filesystem.

Definition at line 409 of file Console.h.

virtual File* ConsoleManager::getRoot ( ) const

inlinevirtual

Returns the root filesystem node.

Implements Filesystem.

Definition at line 389 of file Console.h.

virtual String ConsoleManager::getVolumeLabel ( ) const

inlinevirtual

Returns a string identifying the volume label.

Implements Filesystem.

Definition at line 393 of file Console.h.

virtual bool ConsoleManager::initialise ( Disk * pDisk )

inlinevirtual

Populates this filesystem with data from the given Disk device.

Returns: true on success, false on failure.

Implements Filesystem.

bool ConsoleManager::lockConsole ( File * file )

Acquire a console master in such a way that it cannot be opened by another process.

Definition at line 111 of file Console.cc.

References ConsoleMasterFile::bLocked, Processor::information(), and ConsoleMasterFile::pLocker.

void ConsoleManager::newConsole	(	char	c,
		size_t	i
	)

Create a new console - /dev/ptyXY -> /dev/ttyXY, where X is and Y is .

Definition at line 31 of file Console.cc.

References Vector< T >::count(), and Vector< T >::pushBack().

virtual bool ConsoleManager::remove	(	File *	parent,
		File *	file
	)

inlineprotectedvirtual

Remove a file given a parent and file, assuming path parsing already completed.

Implements Filesystem.
