Here's what seems to be another bug in curses under HP-UX. The HP-UX
OS version:
$ uname -a
HP-UX corona A.B7.00 U 9000/855 707402991
$
The C program:
#include <curses.h>
main()
{
WINDOW *use, *comment;
initscr();
comment = newwin(2, 0, 5, 1);
use = newwin(1, 28, 9, 1);
mvwaddstr(comment,
0,0, "mvwaddstr(use, 0, 0, \"this is a long message\\n\")\n");
wrefresh(comment);
mvwaddstr(use, 0, 0, "this is a long message\n");
wrefresh(use);
sleep(5);
mvwaddstr(comment,
1,0, "mvwaddstr(use, 0, 0, \"short message\\n\")\n");
wrefresh(comment);
mvwaddstr(use, 0, 0, "short message\n");
wrefresh(use);
endwin();
}
With TERM=vt100, this writes "short" over "this ", leaving line 9 reading
shortis a long message
Here is a dump of the output:
0000000 033 [ m 033 [ H 033 [ 2 J 033 7 033 [ 1 ;
0000020 2 4 r 033 8 033 [ 5 B m v w a d d

0000220 a g e \ n " ) 033 [ 1 0 ; 2 H s h
0000240 o r t \t \t \b \b \r 033 [ 1 4 B
And here is an untic of the vt100 terminfo entry:
vt100|vt100-am|dec vt100,
am, xenl,
cols#80, it#8, lines#24, vt#3,
bel=^G, cr=\r, csr=\E[%i%p1%d;%p2%dr, tbc=\E[3g,
clear=\E[H\E[2J, el=\E[K, ed=\E[J, cup=\E[%i%p1%d;%p2%dH,
cud1=\n, home=\E[H, cub1=\b, cuf1=\E[C,
cuu1=\E[A, blink=\E[5m, bold=\E[1m, rev=\E[7m,
smso=\E[7m, smul=\E[4m, sgr0=\E[m, rmso=\E[m,
rmul=\E[m, kbs=\b, kcud1=\EOB, kcub1=\EOD,
kcuf1=\EOC, kcuu1=\EOA, rmkx=\E[?1l\E>, smkx=\E[?1h\E=,
cud=\E[%p1%dB, cub=\E[%p1%dD, cuf=\E[%p1%dC, cuu=\E[%p1%dA,
rs2=\E>\E[?3l\E[?4l\E[?5l\E[?7h\E[?8h, rc=\E8, sc=\E7, ind=\n,
ri=\EM, sgr=\E[%?%p1%t;7%;%?%p2%t;4%;%?%p3%t;7%;%?%p4%t;5%;%?%p6%t;1%;m, hts=\EH, ht=\t,
I see nothing wrong with the terminfo entry. What's wrong with curses?

This bug seems to be identical to a bug I reported a few weeks ago on
this group. The solution is to use a different curses library. If you
have 6.5 that works fine, so will - hopefully - 8.0.
