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 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)

clrtoeol
clear(3NCURSES)clear(3NCURSES)NAME
erase, werase, clear, wclear, clrtobot, wclrtobot, clrtoeol, wclrtoeol - clear all or part of a curses window
SYNOPSIS
# include <curses.h>
int erase(void);
int werase(WINDOW *win);
int clear(void);
int wclear(WINDOW *win);
int clrtobot(void);
int wclrtobot(WINDOW *win);
int clrtoeol(void);
int wclrtoeol(WINDOW *win);
DESCRIPTION
The erase and werase routines copy blanks to every position in the window, clearing the screen.
The clear and wclear routines are like erase and werase, but they also call clearok, so that the screen is cleared completely on the next
call to wrefresh for that window and repainted from scratch.
The clrtobot and wclrtobot routines erase from the cursor to the end of screen. That is, they erase all lines below the cursor in the win-
dow. Also, the current line to the right of the cursor, inclusive, is erased.
The clrtoeol and wclrtoeol routines erase the current line to the right of the cursor, inclusive, to the end of the current line.
Blanks created by erasure have the current background rendition (as set by wbkgdset) merged into them.
RETURN VALUE
All routines return the integer OK on success and ERR on failure. The SVr4.0 manual says "or a non-negative integer if immedok is set",
but this appears to be an error.
X/Open defines no error conditions. In this implementation, functions using a window pointer parameter return an error if it is null.
NOTES
Note that erase, werase, clear, wclear, clrtobot, and clrtoeol may be macros.
PORTABILITY
These functions are described in the XSI Curses standard, Issue 4. The standard specifies that they return ERR on failure, but specifies
no error conditions.
Some historic curses implementations had, as an undocumented feature, the ability to do the equivalent of clearok(..., 1) by saying touch-
win(stdscr) or clear(stdscr). This will not work under ncurses.
This implementation, and others such as Solaris, sets the current position to 0,0 after erasing via werase() and wclear(). That fact is
not documented in other implementations, and may not be true of implementations which were not derived from SVr4 source.
Not obvious from the description, most implementations clear the screen after wclear even for a subwindow or derived window. If you do not
want to clear the screen during the next wrefresh, use werase instead.
