I tried #1, still got 0.0.0.0 with it.. As far as #2, the issue is that I want to know what machine it is, so I don't know what to ping (and in any case, there's no need for me to ping it, since if...

jim,

I'm a bit confused. If the client attempts to do a 'bind', won't it get an error that it's already in use?

There's plenty of stuff before it and after, but I figured all I needed to show was the accept. (Since the socket is working fine, just thought it was how I was printing or accessing the sin_addr...

Hi,

I've inherited some code in C that acts as a server and receives requests over a socket. That is all working fine. I wanted to make a very small change to the server code to print out the...

Show us the code where you are requesting and accepting the string to begin with, then we'll show you how to modify it for the error checking.

if x is 6 and y is 2, then the result is 0.

If you want to make sure there are no numbers in a string, you can do a find_first_of( "01234567890"). If it equals anything other than string::npos, it's got a number in there.

The URL's don't work.

I guess the main question I have is how to define a variable that is not shared among threads inside a function that is used by a thread...

I figured out a way to do it, just not sure if it's the right way. Let me know what you guys think:
Temp.cpp

extern "C"
{
#include "pthread.h"
#include "Thread.h"
}
#include <iostream>...

I modified Thread.h to add the pthread_self() which shows which thread id it has...


#include "stdio.h"
#include "Temp.h"
pthread_mutex_t ilock;
void * myTest(void * arg)
{
char * test =...

Hi Guys,
So I'm trying to experiment with threads, though I'm running into some problems. Basically I'm trying to create multiple threads, where each thread is passed a different set of data. In...

Faced with the choice of code and no question vs. a question with no code, I prefer the former... ;)

I was able to figure it out by doing 'man lfcompile', which told me about 'getconf'. I then ran getconf LFS_CFLAGS and got
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64

Once I compiled with these...

I am trying to write a large file, but it always stops writing when it hits 2GB. (2147483647 bytes to be exact). I know it's not an O/S or disk issue (I'm on solaris) as I'm able to use the mkfile...

I claim no credit, it's one of daniweb's choices...

Try this one out:

#include <iostream>
#include <sstream>
using namespace std;
int main()
{
string numerator;
string denominator;
string myNum;

vicky_dev,

I'm still not sure what you want in terms of an answer. Is it basically 2 numbers that when divided end up with your original value? (ie 433 % 100 = 4.33?)

I'm probably missing some math aspect here, but couldn't you convert 4.33 to a string, find out what position the . is and have your answer?

Is there a function that I can use that given a few vectors which elements are common to all?

for example
vector<int> a;
vector<int> b;

a.push_back( 1 );
a.push_back( 2 );
a.push_back( 3...

Also,

What's the command line you are using to run it?

Can you provide more code? (Also, calling atof for a double maybe a bad idea - losing precision/etc).

need () around if:
if ( any == 0 )

also, you want == not =

There's also sprintf and using iostringstream. All depends on language, preference, and context.

Now the next step is to make the user pass in a year at the command line, etc.

Too lazy - here's the corrected code:

#include <stdio.h>
int main (int argc, char * argv[])
{
switch (1066)
{
case 1066:
printf( "Battle of Hastings\n");
break;

Why is main commented out? and after you comment it out, why does it have a semicolon? And why are there no colons after each case statement? And why is default spelled wrong?

See this - you can by using pointers.
http://www.eskimo.com/~scs/C-faq/q4.11.html

It all depends upon how the functions are defined. Look up 'passing by value' vs. 'passing by reference'.
not all functions return a value. Any function defined as such:

void functionName() or...

What's the point of this statement? You don't return something else instead and you don't perform any logic...

if ((index < 1) || (index > size())){
// can't retrieve something that isn't there...

Is it just a typo in the post or is the object called Patient with a capital P and the class methods are using patient with a lowercase p?

again, print out ch inside the default: of the switch.

For the switch, print something out in the default (for example, print out the value of ch to see what value was passed...)

NO - you missed my point - I meant when RUNNING the program, not the code for example. Instead of:

MyProg this is my path this is my file.txt

you should run:

MyProg "this is my path"...

Does your filename or path contain a space? If so, make sure to pass it inside double quotes...

Basically, you're going to have to post your existing code to show that you've put in some effort.

It's not just windows - I believe AIX is the same way.

In my opinion, this is a pretty silly request - in any case, tell us the headers you've already included so we can come up with a way given the methods already provided.

Yes, just look at the other members of the tm struct.

I'm using doubles for now (fmod is working nicely). Thanks.
