Re: Using SO_RCVTIMEO in Sockets program to implement a receive timeout

Scott,
Thanks.
I had seen that article when I was first starting to get my feet wet with
sockets (only a week ago ... seems like forever).
I will go over that and attempt to implement it.
As always, you help is greatly appreciated.

Jeff,

I do not recommend the SO_RCVTIMEO option. Instead, please use the
techniques in this article:

Click "print" on the article to fix the code formatting. The code is
formatted better in the "printer friendly" version of the article.

I have researched this on the net and found that using the SO_RCVTIMEO
option in the SetSockOpt function, but am not sure how to setup the values
and pass them to it.
This is the code that I have found:
tv.tv_sec = 30; /* 30 Secs Timeout */
tv.tv_usec = 0; // Not init'ing this can cause strange errors

setsockopt(sockfd, SOL_SOCKET, SO_RCVTIMEO, (char *)&tv,sizeof(struct
timeval));

What I am not sure of is how to pass the values shown after the
SO_RCVTIMEO.

TIA,
