Question about procfs function

Question about procfs function

[Leonardo Henrique Machado]

Where can I find a complete tutorial about procfs?

I need to print a whole table in a procfs file.
I have created the file but I cannot understand
one of it's functions:

proc = proc_net_create(procfs_name, 0, procfs_getinfo);

procfs_getinfo is a very confusing function! I would like
to save a linked list in a buffer and after that I'll print
it in the procfs buffer file.

I know that procfs_getinfo (or whatever name you gave it)
must return a integer representing the size of the buffer
that will store my table. Anyway, where can I find good
tutorials and examples about using this procfs buffer
function?

Is there a better place to ask about it?


//leoh
main(){int j=1234;char t[]=":@abcdefghijklmnopqrstuvwxyz.\n"
,*i = "iqgbgxmlvivuc\n:wwnfwsdoi"; char *strchr(char *,int);
while(*i){j+=strchr(t,*i++)-t;j%=sizeof t-1;putchar(t[j]);}}

This question is not netfilter related at all, better the linux kernel
maillist, anyway have a look at:

Linux Device Drivers, 2nd edition
http://www.xml.com/ldd/chapter/book/

and

Linux Kernel Modules Programming (mostly for kernel 2.2, so some things
won't work for your 2.4 and 2.6 kernel but it's a reference anyway).

http://www.faqs.org/docs/kernel/

I think that there's some examples in those docs.
