(I've redirected this to -questions, since -ports is more about issues related to the FreeBSD "ports" mechanism than issues with a piece of software being ported) > I've just bought a QuickCam and found some software for Linux made for it. > > Is there already a port of QuickCam dedicated softwares to FreeBSD ? I can't answer this but I believe the answer is no; there is some discussion of QuickCam requiring an NDA (non disclosure aggreement) to release the programming info. Search the mailing list archive at http://www.freebsd.org/search.html. I found this connectix URL there in one of the articles: http://www.pcworld.com/connectix/qcfaqw.html > If not, I'm in the process of porting some utilities but I'm stopped by the > Linux proprietary function "ioperm" which grants direct access for applications > to I/O ports. What is the equivalent on FBSD ? Once you open "/dev/io" you can access all I/O ports directly. There is no fine-grain mechanism. The man page is missing everywhere except the newest releases, however, it is straightforward - ensure /dev/io exists, set the protection modes up appropriately for your application, and open the device before trying to use the inb/outb inline functions found in machine/cpufunc.h. -- Peter Dufault Real-Time Machine Control and Simulation HD Associates, Inc.
