the gotoxy(int x, int y) function

Hi
Are there any definitions of the gotoxy function on the internet. My
compiler doesn't define it in any header

Your compiler may not, but you operating system headers might. Try an
OS specific group.

There's no such function in standard C. It's undoubtedly part of some
system-specific library. In fact, it's very likely that there are
several such functions in different libraries that do different
things.

You'll need to find and install whatever library provides it.

<OT>The <conio.h> header declares such a function; presumably it
exists only on Windows-like or DOS-like systems.</OT>

gotoxy is not a standard C library function, so many C
implementations do not come with it. Also, see the C FAQ:

10.11: I seem to be missing the system header file <sgtty.h>.
Can someone send me a copy?

A: Standard headers exist in part so that definitions appropriate
to your compiler, operating system, and processor can be
supplied. You cannot just pick up a copy of someone else's
header file and expect it to work, unless that person is using
exactly the same environment. Ask your compiler vendor why the
file was not provided (or to send a replacement copy).

No.
If you have a screen display then almost certainly there will be an
equivalent. So just write gotoxy() to call it.
This almost never affects printf() and the other standard functions. They
treat output as a stream. However there is usually a non-standard printat(),
ConPrintf() or similar that treats the screen as a raster of characters, and
has its own cursor and colour state.

Under the windows OS, lcc-win32 provides a compatibility library with
that function. It uses the console API of windows.

Under linux there are several libraries that provide that function,
specially the "curses" library, that makes for a portable interface
to the console/terminal.

Usual disclaimers apply.

I would guess that any Windows compiler would provide something
similar. Is lcc-win32 unique enough in this regard to be worth
mentioning here?

I don't believe curses provides anything called "gotoxy". Also,
curses is a higher level interface than the Windows console API, so
moving the cursor to an arbitrary location (which I presume is what
the OP is looking for) doesn't necesssarily mean what you might think
it does.

The OP should ask in a system-specific newsgroup, after reading
question 19.4 in the comp.lang.c FAQ, <http://www.c-faq.com/>.

I took a look at that. The code assumes ANSI escape sequences. That
may be a fairly safe assumption these days, but since Unix provides
termcap and/or terminfo, which allow for terminal independence,
there's not much point in doing that.

And the function wastefully builds the string to be printed once piece
at a time using sprintf and strcat. The whole thing could be replaced
with this:

void gotoxy(int x, int y)
{
printf("\033[%dd\033[%dG", y, x);
}

for Windows: http://www.daniweb.com/forums/thread11071.html

The sample gotoxy() implemntation starts with '#include <iostream.h>',
a C++-specific header, though I don't see that it uses anything from
it. (I'd mention that it really should be '#include <iostream>' if it
were topical.)

hi everybody,
im a newbie here and to the C language, i understood your problem, as
far as i know its in the conio.h header file both in C and C++, i have
checked it, so if you want to use it, you can simply include the file.
Well if i'm wrong somewhere please let me know so that i can correct
myself.
Thank you

I do not know. The library is a clone of the old turbo C of Borland
with the same interface. As far as I know, MSVC does not provide it,
gcc under windows doesn't either, but I do not know ALL windows
compilers either.

The snag is that many platforms don't have a conio.h. It's non-standard.

That doesn't mean that it is a bad thing to use the conio functions, however
your program will not them work when transferred to another machine.
stdio.h, on the other hand, is ANSI.

There's always some way to move the cursor about the screen, even if you
curse the cluntzy interface.

Not all implementations have a cursor. Not all of those that do are
able to move it to arbirary locations.

 

[Richard Bos]

Your compiler may not, but you operating system headers might.

Not very likely. It's a conio function, which is almost always used with

M$ operating systems, which don't come with OS headers or libs.

What Albert needs to do is to figure out what he _really_ wants to do,
not which function he believes he is expected to use; and _then_
consider which newsgroup that would be topical in. Here it isn't.

gotoxy and conio are not present on standard C compilers (the
subject of this newsgroup) and are thus off-topic here. Find a
newsgroup that deals with your peculiar system.

IMHO It doesn't make much sense in a multi-Window environment. goto
x,y on which window ? On the entire desktop? On my nth virtual
desktop? x,y measured in pixels, pels, inches, glyphs? measured top
down (like Excel) or bottom up?

It made perfect sense in the good old DOS days when you had exactly
one window.

yawn - another technologically obsolete remark
(headers and libraries have been a free download for many years).

And in those instances, we wouldn't be discussing how to use gotoxy() ...
