The problem is that printf's scroll off the screen. How can I write to a file? ----- Original Message ----- From: "Daniel O'Connor" <doconnor@gsoft.com.au> To: "Gurpratap Virdi" <gvirdi@gvirdi.com> Cc: <hackers@FreeBSD.ORG> Sent: Friday, March 30, 2001 8:18 AM Subject: RE: Writing to a file in the kernel On 30-Mar-01 Gurpratap Virdi wrote: > I am trying to debug some modifications I made to the kernel.

You can also add a debugging ioctl to your device, or a sysctl to change the debug level mid stream. --- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
