Take a look at the two command below.
The first will give you your terminal size in lines, columns.
IF your terminal can do it, (xterm for example), the second will auto adjust it for you...
The 24 and 80 in the 'printf' statement can be anything to ALMOST the size of your desktop...
I want to get the screen width and cursor positions.
When I used curses, all the screen content was cleared.
So Can I use curses to get the screen size without clearing anything in the window?
Or is there any other alternative???
I can use only C or C++. (0 Replies)
Hi,

Hi to all!
I'm a teacher of maths and physics in an italian high school in Milan, Italy.
I need a simple program that read the position of mouse cursor in function of time and write the coordinates in a text file. The time resolution have to be something like 1/10 sec or better (I have to know... (2 Replies)
hi all,
am trying to modify a ksh script to group server names together depending on the cluster they sit in. currently the script does a
find . -name '*.pid'
to find all running servers and prints out their pids and names.
current output looks something like this :

I need to get the cursor position, and put it inside a variable. Problem is, i don't have the tput command, or ncurses.
Apparently I was supposed to try the following:
echo -e '\E
But I don't get a value or anything. Please help. (3 Replies)
Hi there.
It's easier to explain this with a pseudo code, I hope this makes sense:
var1=hello
echo $var1
some kind of loop
echo loop counter
done
How do I hold the cursor position immediately behind the last output so I'd get something like:
hello123456789
DOS used to use ","... (5 Replies)

resize_term
resizeterm(3X)resizeterm(3X)NAME
is_term_resized, resize_term, resizeterm - change the curses terminal size
SYNOPSIS
#include <curses.h>
bool is_term_resized(int lines, int columns);
int resize_term(int lines, int columns);
int resizeterm(int lines, int columns);
DESCRIPTION
This is an extension to the curses library. It provides callers with a hook into the ncurses data to resize windows, primarily for use by
programs running in an X Window terminal (e.g., xterm). The function resizeterm resizes the standard and current windows to the specified
dimensions, and adjusts other bookkeeping data used by the ncurses library that record the window dimensions.
Most of the work is done by the inner function resize_term. The outer function resizeterm adds bookkeeping for the SIGWINCH handler. When
resizing the windows, resize_term blank-fills the areas that are extended. The calling application should fill in these areas with appro-
priate data. The resize_term function attempts to resize all windows. However, due to the calling convention of pads, it is not possible
to resize these without additional interaction with the application.
A support function is_term_resized is provided so that applications can check if the resize_term function would modify the window struc-
tures. It returns TRUE if the windows would be modified, and FALSE otherwise.
RETURN VALUE
Except as notes, these function return the integer ERR upon failure and OK on success. They will fail if either of the dimensions are less
than or equal to zero, or if an error occurs while (re)allocating memory for the windows.
NOTES
While these functions are intended to be used to support a signal handler (i.e., for SIGWINCH), care should be taken to avoid invoking them
in a context where malloc or realloc may have been interrupted, since it uses those functions.
If ncurses is configured to supply its own SIGWINCH handler, the resizeterm function ungetch's a KEY_RESIZE which will be read on the next
call to getch. This is used to alert an application that the screen size has changed, and that it should repaint special features such as
pads that cannot be done automatically.
If the environment variables LINES or COLUMNS are set, this overrides the library's use of the window size obtained from the operating sys-
tem. Thus, even if a SIGWINCH is received, no screen size change may be recorded.
