Thank's guy's for answering . I found your word's useful. I'm getting over the project , everithing seem's more clearly now.
I have a few things to acommodate and everithing seem's to work just fine.
I only have a question for you.I found myself in a situation , I cannot resolve . Maybe I haven't think for the right choice yet , but you can help me ..
I written the server and client code , for some sort of messenger ( mini-version ) , and I don't know ( I may know , but not having the right idea ) , how to implement something.
I want to make an easy thing.In the source code for the client , I want to implement someting like this :
-when the client want's to transmit data , it gets the buffer ( getstr(buffer) )
-when something arive at the client , some data , it 's print's the string's arived on main window.
I cannot implement this.How can I implement this in C ? I write some sort of code , down :
Code:
int nbytes;
for (;;)
{
if (nbytes=recv(listener,buf,sizeof(buf),0) >0 )
{
printw("%s\n",buf);
refresh();
}
else{
getstr(s);
send(listener,s,sterlen(s),0);}
}
The problem , is that this code , is how you see , non-useful and childish.
I want something simple , when I write data , on the client ( getstr(s) ) , to be sent ( to listener -> server ) and when I receive some data ( string's ) , to be printed on the main window.This is all.
The problem is that I cannot make this ..it block's .If I don't enter a string to be sent to the ( listener -> socket server ) , it won't print ( received data ).
Should I use files ?.. or something like that ..
A help , may be needed , if you guy's get the idea , what I want
A very n00b question: After compiling and installing software, where does the original source code reside? I'd like to study the source code of some of the ports I've installed. Thanks! :D (1 Reply)
I'm new to PERL, but I want to take the page source and write it to a file or standard output. I used perl.org as a test website. Here is the script:

gvrng
gvrng(1)gvrng(1)NAME
gvrng - An interactive, introductory programming language.
SYNTAX
gvrng [world file | program file]
DESCRIPTION
Guido van Robot is a project developed by advanced high school students for use by their peers as a learning tool and precursor to the fur-
ther study of programming with Python. It is a minimalistic programming language providing just enough syntax to help students learn the
concepts of sequencing, conditional branching, looping and procedural abstraction. It's biggest strength is that it permits this learning
in an environment that combines the thrill of problem-solving with instant visual feedback. In short, it is an interactive, introductory
programming language that is excellent for learning the basic concepts of programming, applicable in any high-level language. Best of all,
it's a whole lot of fun, too!
At this point, you are probably asking yourself, "What is GvRng, specifically?" The gist of it is that it is a robot represented by a tri-
angle on the screen that moves around in a world made up of streets and avenues, walls and "beepers", which Guido can collect or set. His
actions are completely guided by a program written by the user.
