dear coders,
i need some inspiration again...
there is something what i always wanted to know... how to code following:
Code:
value 1: __________
value 2: __________
important: when my "script" starts the display has to be cleared and two lines are shown (see above), the cursor has to be positioned above first underscore in first line. when i start to write username, the underscore(s) has(have) to remain there! when i hit enter or tab, the cursor is positioned above the first underscore in the second line.
ideally the chain of underscores will look like a line
how would the C code look?
will i have to use ncurses?
kind regards

SunOS5.8 is a radical departure from SunOs4.X in many ways. one of the important differences is the handling of devices. Adding devices under SunOS4.x required a kernel reconfiguration, recompliation and reboot. Under SunOS5.X, this has changed with the ability to add some drivers on the fly.... (1 Reply)
I know pipelined processors have issues with interupts.... but why? And does the architecture of the CPU affect the kind of software that can run on it?

I am curious about one thing.
Lets say I have a file file-a to which new generations are created on demand by simply archiving it (ex: file-a.tar.gz) and having the new one created with the same original filename file-a.
Now what I want to know is if I create a hard/soft link to file-a, what... (1 Reply)

I have a directory containing a series of files of the format:

movenextch
curs_alecompat(3CURSES) Curses Library Functions curs_alecompat(3CURSES)NAME
curs_alecompat, movenextch, wmovenextch, moveprevch, wmoveprevch, adjcurspos, wadjcurspos - these functions are added to ALE curses library
for moving the cursor by character.
SYNOPSIS
cc [ flag ... ] file ... -lcurses [ library .. ]
#include <curses.h>
int movenextch(void);
int wmovenextch(WINDOW *win);
int moveprevch(void);
int wmoveprevch(WINDOW *win);
int adjcurspos(void);
int wadjcurspos(WINDOW *win);
DESCRIPTION
movenextch() and wmovenextch() move the cursor to the next character to the right. If the next character is a multicolumn character, the
cursor is positioned on the first (left-most) column of that character. The new cursor position will be on the next character, even if the
cursor was originally positioned on the left-most column of a multicolumn character. Note that the simple cursor increment (++x) does
not guarantee movement to the next character, if the cursor was originally positioned on a multicolumn character. getyx(3CURSES) can be
used to find the new position.
moveprevc() and wmoveprevch() routines are the opposite of movenextch() and wmovenextch(), moving the cursor to the left-most column of
the previous character.
adjcurspos() and wadjcurspos() move the cursor to the first(left-most) column of the multicolumn character that the cursor is presently on.
If the cursor is already on the first column, or if the cursor is on a single-column character, these routines will have no effect.
RETURN VALUE
All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion.
