Please cc your reply to my email a/c. thanks --Vasudha ---------- Forwarded message ---------- Date: Thu, 15 Jul 1999 14:42:34 +0800 (SGT) From: Vasudha Ramnath <v...@krdl.org.sg> To: freebsd-questi...@freebsd.org Subject: implementing poll() in a device driver I'm running FreeBSD 3.1-RELEASE. Could someone explain what the poll() function in a device driver should do ? Can it return POLLERR or POLLHUP ? I have a test driver that returns these values from the poll() function. However, the application that called the select() is not getting an error. Instead, the select is returning that the particular file descriptor is, in this case, 'readable' ! Am I missing something ? Any insight appreciated. thank you --Vasudha To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-questions" in the body of the message To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
