Hi there,
In the process of setting up webcams (and getting greatly frustrated)
I have been using mknod to create device entries. This is something
I'm not really familiar with and I have some questions. I am trying
things at present and don't really know why I am typing stuff I find
in Google!
Questions:
1) How are major and minor device numbers assigned? e.g. a webpage
will say type "mknod /dev/video0 c 81 0". I understand the syntax but
why 81 and 0 for the major and minor numbers?
2) How do these devices you create interact with udev? Permissions and
other things seem to disappear after a reboot. Should I be using udev
instead of mknod?
URLs to articles would be appreciated or just people's comments. I
promise to Wiki what I find out as I have been doing for most of my
discoveries...
