Need some suggestion about Socket Programming use C

Hi,

I am a student who just begin to learn socket programming use C. And I will finish a project about this.
So I want to learn it at first and know some basic things about this.

I will program it and test and run it in my University's FreeBSD server.
And I found that there is only VI editor for me to use.
It's hard to use.
also hard to debug my program.

Any suggestion about this?

How can I write code and debug it efficiently?

Thank you all guys so much.
my English is poor, sorry for that!

You must learn the vi first to use it , Then you will feel like no editor is comparable to vi.
there are several options are available in vi to find the error by seeing itself.

Possibly you can install many vim plugins at free of cost.

First you try with this

:syn on

which enable the syntax ON.

For more understanding of vi refer :

Some people just don't appreciate anything

You probably have the full fledged "VIM" (type: vim) since vi is just a simplified version

Re: debugging -- check and see if you have "gdb" available.

I believe FreeBSD is historically the origin of the C socket, anyway it will not be a problem, you are doing unix style socket programming.

Hi buddy! If u want to know the basic things about vi editor just give the vimtutor command.
It will help you to get familiar in vi editor. For flexible debugging on your code you can use ddd command

Thank you very much!
But I have not root authority for Server. So I cannot install plugin.
still thank you so much.

also hoping more other suggestion

Plus, another trivial question..
If I wanna delete one character in VI due to typo...what is the quickest way to do so?
my way is:

1 press "esc"
2 press "x"
3 press "a"
then go back coding ..

am I right or do redundant operation?

[thillai_selvan]

if u want to delete more characters consider the following example
this is for testing
Your cursor is in 'e' in the word "testing" if u pressed D then it will delete up to the last character in that line

[thillai_selvan]

At first you have to be in esc mode. so press esc. And then press 'D' key for deleting up to the last character in that line.

VIM will probably be a lot more useful with a ".vimrc". You have an account on the server, it is a plain text file in your ~ (home) directory. If you google "vimrc" you'll find stuff. VIM documentation is chaotic but there's lots of it online.

Here's a totally excessive .vimrc that should take a few months to decypher:
The ultimate Vim configuration (vimrc)

Here's a more minimal example:

:syntax enable
command SpellOn setlocal spell spelllang=en_us
command SpellOff setlocal nospell
" spell suggest: z=

set number
set nowrap
set bs=indent,eol,start         " allow backspacing over everything in insert mode
set list listchars=tab:\|_,trail:-
set tabstop=4
set shiftwidth=4
set wildmenu
set ruler
set virtualedit=all             " virtual space at line end
set hlsearch            " highlight search hits
set autoread            " update when file is altered elsewhere

Just use backspace or delete. You may have to set this line in the aforementioned .vimrc:

set bs=indent,eol,start         " allow backspacing over everything in insert mode

Hopefully you understand
insert VS command (aka. escape) mode
at this point.

If not, DO NOT PASS GO! That's not a link, you'll have to google.

filetype plugin indent on

Please add the above line too in that .vimrc file.
It will make clear alignment in ur code automatically when u r writing your code.
You don't have to worry about making indention in your code.

[Rede]

yes, I understood insert VS command (aka. escape) mode. no problem
I have create .vimrc On server under my directory. paster those code you gave me.
But nothing changed...How it gonna to work?

[thillai_selvan]

can you tell me where you have created that vimrc file?
It should be under your /home/ directory. i.e. /home/rede/.vimrc.
Am I correct?

[MK27]

Here's a test. Add this to the .vimrc:

:imap <F4> for (i=0;i ;i++)

Now press F4 in INSERT mode. The blue part should appear.

You have to restart vim first. If this does not work, email the system administrator.
