wide-character getch ()

[Barguast]

Is there a wide-character version of C's getch () function? I've tried getwchar () but it doesn't seem to work

[sw_is_great]

what do u mean by wide-character version of getch()

use scanf or gets for getting more than 1 character

[Barguast]

I mean something like getch () which will return a WCHAR. I need to detect arrow key presses, and while I know how to interpret them (a leading NULL character) it seems bet to just use a WCHAR.
So far, I'm using the following function, but I'd much prefer a standard function:

WCHAR CConsole::ReadKey ()
{
	if (!kbhit ()) return 0;

	char lowCh = getch ();
	if ((lowCh == -32) || (lowCh == 0)) // Arrow key or Function key
		return ((getch () << 8) + lowCh);
	else
		return (WCHAR) lowCh;
}

_getwch

getch is a wrong name btw, it should be _getch.

[Barguast]

there's nothing in the MSDN library about _getwch () and I'm unable to use it (Undeclared Identifier).
Do I have to include a specific header? I've tried to find this myself, but everywhere say to use <conio.h> which doesn't work either.

why getch is a correct name and u need to include conio.h

U can use keyboard interrupts to get the scan code for each key.U know that each key(including entre,F1......F12) have a unique scan code . u can use that..


for this use int86 function..

[CornedBee]

getch is a non-ANSI function. Therefore it should be prefixed with _. I believe MS does that, but it also provides the non-conforming name getch for compatibility with older apps, unless you enforce ANSI compatibility with the /Za compiler switch.

_getch and _getwch are documented in my VS.Net 2003.

I'm still getting an 'undeclared identifier' error when i include this... I'm using MS Visual Studio 6.0 - could I have an outdated header file or something?

[sw_is_great]

post ur code

should be something like

#include<stdio.h>
#include<conio.h>
main()
{
printf("\n Screen wait for me");
getch();
}

[Barguast]

it's not _getch () I've got a problem with, it's _getwch ().
Having tried the code you posted, but using _getwch () instead, I still get an undeclared identifier error for using _getwch ().

For trapping keyboard hits including enter key etc , use keyboard interrupts -

they are fast
reliable

...and don't work in real Win32 apps.
