I hope I'm asking in the right newsgroup: 1) What is the effect (from a user-space application programmer's point of view) of using the MAP_HASSEMAPHORE flag when calling mmap(...)? 2) And why is there no equivalent flag when using shmget(...)? I tried reading the manuals+web, but since in Linux there is no equivalent MAP_HASSEMAPHORE flag, I couldn't find much information about it. Thanks in advance! _________________________________________________________________ Protect your PC - get McAfee.com VirusScan Online http://clinic.mcafee.com/clinic/ibuy/campaign.asp?cid=3963 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
