Sorry, but stackoverflow is *not* a good source to cite when talking about POSIX standard. Instead, I prefer to search opengroup.com and on the 'setsockopt' page google gives me (https://pubs.opengroup.org/onlinepubs/000095399/functions/setsockopt.html), I find this in the description of SO_RCVTIMEO: "The default for this option is zero, which indicates that a receive operation shall not time out." BTW, even the stackoverflow page you cited says: "If the timeout is set to zero (the default) then the operation will never timeout".
