The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Function - skb_copy_and_csum_datagram_iovec

Asked by Xephyr in Linux Programming

Tags:

I am going to program a low-level network app and I need to manipulate some code in the kernel (version 2.4.18). The problem is that I traced a network function back to its roots, which ended up in an external function call ( skb_copy_and_csum_datagram_iovec ). I searched all the files in the kernel in order to find this function's place. I thought it was in usr/src/linux-2.4/include/linux/skbuff.h but there is only an "extern int" definition for this function there so I cannot trace what this function does and where it is really located.

I was looking for such a field

skb_copy_and_csum_datagram_iovec (const struct xxx, int xxx, char xxx, u32 xx)
{
x
x
x
x
x
return x; (BTW I know that it returns some value - not void - so most probably it is an int type definition)
}

so that I could see what the function is all about, but it is strangely nowhere in the source... Any pointers on where I can find this single function in the kernel's source code ?Start Free Trial
