I need to change the TOS field of all packet I send. I am not use to program I do not success to make operated this code.
<br />
WSADATA WSAData; <br />
WSAStartup(MAKEWORD(2,0), &WSAData); <br />
<br />
SOCKET sock; <br />
SOCKADDR_IN sin; <br />
sin.sin_addr.s_addr = inet_addr("192.168.4.33");<br />
sin.sin_family = AF_INET;
sin.sin_port = htons(10000);
<br />
sock = socket(AF_INET, SOCK_RAW, 0); <br />
bind(sock, (SOCKADDR *)&sin, sizeof(sin));
<br />
int TOS=0x80; <br />
<br />
while(1)<br />
{<br />
setsockopt(sock, IPPROTO_IP, IP_TOS, (char *)&TOS, sizeof(TOS));<br />
<br />
if (setsockopt(sock, IPPROTO_IP, IP_TOS, (char *)&TOS,<br />
sizeof(TOS)) == SOCKET_ERROR)<br />
printf("\nWarning: Fail to set TOS value: error - %d",<br />
WSAGetLastError());<br />
} <br />
system("PAUSE");<br />
return EXIT_SUCCESS; <br />
}<br />
Someone would have a solution? I just try to modify TOS field at the value 0x80 using the function setsockopt().

So do you know an other issue to mark all TOS IP header fields from all outcoming packets?

which is the best way to read a line from a text file in c.. the size is not known. and this text needs to be stored in a CString.

If you're reading it in C, then you can't store it in a CString (C++).
For MFC, you can use CStdioFile and its member function ReadString.
In C, it's a bit harder - you have no idea about the buffer length for your TCHARs (you are using unicode compatible code, I hope...), so you're going to have to keep the current file pointer, read through the file until you hit the end, or a carriage return, calculate the size, rewind, then read the string.
Or read the whole file into memory, and act on it as a big chunk of ram, which will be similar, but faster.
And now someone will come along and tell you to use
WinReadStringFromFile (...); (Made up name, before you look for it)
Good luck,
Iain.

That would all depend on how the file was opened.

Unless the file is still being written to, how can you not know its size?

Hi,
What is the difference between
#include "math.h" and
#include <cmath> </cmath>
and which is better?
Thanks & Regards,
Suman

first remove HTML support from your question!
#include<math.h> search for file in path configured in project setting/development env setting
#include "math.h" also search current directory including project/ developement env setting

Maybe a minor difference, using the quotes the searches first in the current directory and then in the project/ developement env setting.
This means that you can overrule include files

Hi,
Thanks for help.
I actually meant "cmath", but it was deleted bacause of the tags.
Thanks,

ohh! CMATH header file is c99 compliant header file, see you don't use .h while including that file!, actually all the function under cmath header files comes under STD namespace!

Hi,
#include "....." is to include the files which are in your current working directory. For eg. if you have created some file which needs to be included in another cpp / c file for using a function or any member the you can use this option.
if u have created a file a.cpp having some generalize function and you want to use this function in every other .cpp program then you can include this source code file in other source code using
#include "a.cpp"
#include <.....> is generally for dev/project Include folders which contains built-in .h files or any other files.

Hello everyone,
All swap functions in STL container class is exception safe and nothrow, right? I have searched for swap for vector and deque, but seems no explicit document about the exception safe level.
thanks in advance,
George
