Detailed Description

3ds stdio support.

Provides stdio integration for printing to the 3DS screen as well as debug print functionality provided by stderr.

General usage is to initialize the console by:

consoleDemoInit()

or to customize the console usage by:

consoleInit()

Enumeration Type Documentation

debugDevice

enum debugDevice

Console debug devices supported by libnds.

Enumerator
debugDevice_NULL	Swallows prints to stderr.
debugDevice_SVC	Outputs stderr debug statements using svcOutputDebugString, which can then be captured by interactive debuggers.
debugDevice_CONSOLE	Directs stderr debug statements to 3DS console window.

Function Documentation

consoleDebugInit()

void consoleDebugInit

(

debugDevice

device

)

Initializes debug console output on stderr to the specified device.

Parameters

device

The debug device (or devices) to output debug print statements to.

consoleGetDefault()

PrintConsole* consoleGetDefault

(

void

)

Gets a pointer to the console with the default values.

This should only be used when using a single console or without changing the console that is returned, otherwise use consoleInit().

Returns

A pointer to the console with the default values.

consoleInit()

PrintConsole* consoleInit	(	gfxScreen_t	screen,
		PrintConsole *	console
	)

Initialise the console.

Parameters

screen	The screen to use for the console.
console	A pointer to the console data to initialize (if it's NULL, the default console will be used).

Returns

A pointer to the current console.

consoleSelect()

PrintConsole* consoleSelect

(

PrintConsole *

console

)

Make the specified console the render target.

Parameters

console

A pointer to the console struct (must have been initialized with consoleInit(PrintConsole* console)).

Returns

A pointer to the previous console.

Examples

audio/filters/source/main.c, audio/streaming/source/main.c, graphics/printing/both-screen-text/source/main.c, and graphics/printing/multiple-windows-text/source/main.c.

consoleSetFont()

void consoleSetFont	(	PrintConsole *	console,
		ConsoleFont *	font
	)

Loads the font into the console.

Parameters

console	Pointer to the console to update, if NULL it will update the current console.

consoleSetWindow()

void consoleSetWindow	(	PrintConsole *	console,
		int	x,
		int	y,
		int	width,
		int	height
	)

Sets the print window.

Parameters

console	Console to set, if NULL it will set the current console window.
x	X location of the window.
y	Y location of the window.
width	Width of the window.
height	Height of the window.
