Dear Monks,
I am learning Curses and Threads, as a simple exercise I have written below code to update a dummy counter at a given row. Program works fine for some time and suddenly the terminal screen starts displaying all weird characters.
Please help me to understand the concept I have missed.
use threads;
use Curses;
use strict;
initscr();
curs_set(0);
box( ACS_VLINE, ACS_HLINE );
my $lthr = threads->create(\&counter, 5);
my $rthr = threads->create(\&counter, 15);
sub counter {
my $pos = shift; #Position:Row
my $lctr = 0;
while(1) {
$lctr++;
move($pos,5);
addstr("$lctr");
napms(100);
refresh();
}
}
$lthr->join();
$rthr->join();
getch();
endwin();
exit(0);

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

are good places to start.
