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

[Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>]

Jeff,

I do not recommend the SO_RCVTIMEO option.   Instead, please use the 
techniques in this article:
http://iprodeveloper.com/rpg-programming/timeouts-sockets

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