Re: [Dev-C++] How to ???

[Cary H. <xen...@gm...>]

Hi all, I hope this will be of some help.

By default, win2k and xp close a console(dos) window when the program
that is using it exits.  In 2k, you can change the behavior of a
window to remain open once the program exits until you close it
yourself.  XP, however, does not have this "feature".  In my
experience, it is easiest to add the call system("pause") right before
the program terminates so that the window remains open.  Another
option is to open the run command, type cmd, and open a console
window, and run the executable that way.

If you decide to go the system("pause") route, remember to add a

#include <stdlib.h> // for c
#include <cstdlib> // for c++

Good Luck! 

Cary Haynie

ps.  on a side note, system() should support any legal dos command,
not just pause.

[Dev-C++] GDB debugging

[Rob L. <rob...@nt...>]

Hey folks I am a newbie to using the GDB debugger so please excuse me =
for asking a simple question
i want to put a watch point on a particular varaible e.g some int =
variable..therefore i will know its run time value
but the problem i have when i set a watch point it says the watch point =
for the particular variable " not found in current context"
can anyone explain what this means? or/and explain to me the proper =
procedure to be able to set a watchpoint on a particular variable & thus =
view its run time value.
any help greatly appreciated & again apologies for my inexperience
regards
Rob

Hi,

This problem sometimes appears in this Mlist, but AFAIK it has no 
straightforward solution
Some workarounds I saw are
-to put as last instruction a 'system("pause")' or a 'getchar()' or 
something similar that wait for an input
-to place the cursor onto the last instruction and use the 
run-until-cursor debug command

These are not the best, because if your code has many exit points (e.g 
in case of error) the window will be closed anyway.

Hoping this help you, I say "goodbye"

Re: [Dev-C++] Sockets API - Newbie - send() function

[Peter D. <don...@ne...>]

Hi Daniel,

So 0 means there are no flags?  This is also from MSDN:

The send 
<http://msdn.microsoft.com/library/en-us/winsock/winsock/send_2.asp> and 
recv 
<http://msdn.microsoft.com/library/en-us/winsock/winsock/recv_2.asp> 
functions both return an integer value of the number of bytes sent or 
received, respectively, or an error. Each function also takes the same 
parameters: the active socket, a char buffer, the number of bytes to 
send or receive, and any flags to use.

 From the man page:
The  flags parameter is the bitwise OR of zero or more of the following 
flags.  So if you use 0 does this mean there are no flags?  But if i use 
one of the flags such as MSG_OOB then I take it the bitwise OR of 
MSG_OOB is not equal to 0?  For that matter is the bitwise of 0 equal to 0?

Is this right?

In the ballpark?

Or am I still on my own planet?

Thanks for your help,

Peter.

You can find Winsock documentation at MSDN; you can also Google for a 
.hlp/.chm help file for off-line reference.
This is from 
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/send_2.asp 
:

---
int send(
  SOCKET s,
  const char* buf,
  int len,
  int flags
);

Parameters

s
    [in] Descriptor identifying a connected socket.
buf
    [in] Buffer containing the data to be transmitted.
len
    [in] Length of the data in buf, in bytes.
flags
    [in] Indicator specifying the way in which the call is made.


(...)


The flags parameter can be used to influence the behavior of the 
function beyond the options specified for the associated socket. The 
semantics of this function are determined by the socket options and the 
flags parameter. The latter is constructed by using the bitwise OR 
operator with any of the following values.

MSG_DONTROUTE     Specifies that the data should not be subject to 
routing. A Windows Sockets service provider can choose to ignore this flag.
MSG_OOB     Sends OOB data (stream-style socket such as SOCK_STREAM only.

[Dev-C++] Sockets API - Newbie - send() function

[Peter D. <don...@ne...>]

Hi,

In the send function as per:

int send( int socket, const char *buffer, int len, int flags );

If I want to send data like the following:

char* string = "hello, internet!";
int sent;
sent = send( datasock, string, strlen( string ), 0);

I understand the first 3 parameters but can someone tell me what the '0' 
is as the fourth parameter to the send function?  (it is probably a flag 
but what does it do?  does it mean there are no flags?)

Many thanks,

Peter.

Now a hint for the Dev-C++ developers: hide the mailing list address

Re: [Dev-C++] wxWidgets Install

[Scott S. <ssi...@sp...>]

WXWIN is an environment variable. You may set an environment variable 
like this:
1. Go to the Control Panel
2. Open the system icon.
3. Click the advanced tab.
4. Click "Environment vairables."
5. It should say "User variables for (USER)" and "System variables". 
Click the new button under user variables.
6. Enter WXWIN for the variable name.
7. For the value, enter the path to the directory where WxWinodws is. 
For example, if you installed WxWindows is C:\WX, enter C:/WX.

Why / instead of \? Although Windows uses \ for file paths, the MinGW 
uses /, just like UNIX and Linux.

Yes. The docs say different things, that's why I asked in the other 
e-mail for the standard...

My offline Winsock 1 reference ("winsock.hlp") says:

---
SOCKET PASCAL FAR socket ( int af, int type, int protocol );

af    An address format specification.  The only format currently 
supported is PF_INET, which is the ARPA Internet address format.
---

The MSDN's Winsock 2 reference for socket() doesn't say a word about the 
constant that should be used.
Some articles there use AF_INET, but reference implementations mostly 
use PF_INET (e.g.: 
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/ipv6_enabled_server_code_2.asp 
).

Then you could also assume that PF_INET == AF_INET == 2, and this can be 
considered right too:

socket(2, 1, 6);   /* "everybody" uses the same values anyways, so this 
is "safe" */


I even found on a Google search people writing references saying that 
the correct way is to use:

socket(AF_INET, SOCK_STREAM, PF_INET);

Now *this one* I know for sure it's wrong, but if you type exactly this 
on a Google search, you'll get some hits of people actually using this.

Yeah, probably.
But anyways, I prefer using PF_INET for a socket() call, so I'll be sure 
that if I need to use the code on a "bizarre" (but working) sockets 
implementation, this can't cause any problem.

Re: [Dev-C++] Question!!

[Per W. <pw...@ia...>]

Trivial exercise. You have a static buffer large enough never to overflow
for the numeric range you receive as input.

You fill in the buffer from the end by taking your number modulo 10 to
find one digit. Then number divided by time to shrink the number.

Continue until number is zero.

Observe to take special care if number was zero from the beginning.

Also take care about negative numbers. Easiest is to set a flag that is
was negative and then negate it and perform above algorithm. In end, check
flag and if needed add a '-' to the buffer.

Return the pointer to the first used character in the buffer.

You could be right. I don't have the standard so I cannot be sure - if I 
am wrong and anyone have more accurate information - please reply.

In Linux socket.h header file you can find:
#define PF_INET		x
#define ...
/* Address families AF_ - same as PF_ */ <== note this

I think we could assume that the values will be always equal. Why? Just 
because there are so many sources using AF_INET (as I found in google 
the PF_INET was added later, so AF_INET was used before) - any change in 
standard will make them not runnable. The only addition will probably be 
adding some other AF_ to one PF_ (many address families for one protocol 
family) but probably it will be done this way:
#define AF_INET		PF_INET
#define AF_SUPERINET	(PF_INET + 1)
#define AF_UNIT		PF_UNIX
to provide compability (this could be not true, it's just my imagination).
The third thing is that socket() (as I found in google) checks for both
AF_INET and PF_INET in function call and for sockaddr address family 
definition too - so probably it the contants change (AF_ not equal PF_) 
the socket() will work good.

This is getting confusing now, the linux manpage lists the PF_ values, but=
=20
refers to AF_ later on.
The BSD manpage I found uses AF_

http://www.neosoft.com/neosoft/man/socket.2.html
..
int
socket(int domain, int type, int protocol)
..
The domain parameter specifies a communications domain within which=20
communication will take place; this selects the protocol family which=20
should be used. These families are defined in the include file=20
<sys/socket.h>. The currently understood formats are
..
AF_UNIX
         (UNIX internal protocols), AF_INET
(ARPA Internet protocols),

AF_ISO....

Hmmmmm.
Also the Win32 docs call this parameter "address family" rather than=20
"protocol family".I don't have access to BSD or POSIX specs so I don't know=
=20
the official line.
It's a mystery.:-)

Re: [Dev-C++] How to ???

[Peter D. <don...@ne...>]

Hi Haim,

I am no expert but I found the following in a book i have.
In your main() function insert the following lines:
std::cout << "Press the enter key to exit";
std::cin.ignore(std::cin.rdbuf()->in_avail() + 1);

This just waits for the user to press the enter key.

Not exactly sure what the std::cin.ignore stuff does as I said I copied 
it from a book :)

Hm... really? From what I remember, it says they are *generally* the 
same, but I may be wrong.
I'm curious now, does anyone know if it's possible to find on the 
internet exactly what the BSD standard says? (for free, obviously... I 
don't want to buy a book, I'm not THAT curious)

You're right, my mistake. AF_ defines are for the sockaddr structures & PF_ 
for the socket call. However most
of the literature uses AF_ for the socket call too. ( Some docs I have 
specifically say to use AF_ defines ).

FYI the above formcompiled and ran fine on Win32, Solaris & Linux.
