Detailed Description

This class holds the file object related to the console, that is set by the board support package, and used to populate /dev/console in DevFs

Member Function Documentation

intrusive_ref_ptr<Device> miosix::DefaultConsole::get ( )

inline

Returns

the currently installed console device, wrapped in a TerminalDevice

DefaultConsole & miosix::DefaultConsole::instance ( )

static

Returns

an instance of this class (singleton)

intrusive_ref_ptr<Device> miosix::DefaultConsole::IRQget ( )

inline

Returns

the currently installed console device. Can be called with interrupts disabled or within an interrupt routine.

void miosix::DefaultConsole::IRQset

(

intrusive_ref_ptr< Device >

console

)

Called by the board support package, in particular IRQbspInit(), to pass to the kernel the console device. This device file is used as the default one for stdin/stdout/stderr. Notes: this has to be called in IRQbspInit(), since if it's called too late the console gets initialized with a NullFile. Also, calling this a second time to dynamically change the console device is probably a bad idea, as the device is cached around in the filesystem code and will result in some processes using the old device and some other the new one.

Parameters

console

device file handling console I/O. Can only be called with interrupts disabled.

void miosix::DefaultConsole::set ( intrusive_ref_ptr< Device >  console )

inline

Same as IRQset(), but can be called with interrupts enabled

Parameters

console

device file handling console I/O. Can only be called with interrupts disabled.
