Counting number of modules in a LKM

[koenb]

inside my LKM I would like to count the number of loaded modules inside the kernel, however the modules list isn't exported. How can I count this?

You can read /proc/modules file inside you kernel if your system support procfs.

I think procfs isn't used a lot nowadays...if procfs isn't supported try cd /sys/module...You will find all modules listed there..

Hi,

If possible can you share the code for doing so.

[the gooey kablooie]

#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>

int main()
{
int count=0;
DIR *stream;
struct dirent *mod;
stream=opendir("/sys/module");
while(1)
{
mod=readdir(stream);
if(mod==NULL)
break;
count++;
}
printf("&#37;d\n",count-2);
}

Use the above code to count number of modules in /sys/module.

P.S. - I have printed count-2 because readdir also reads the "." and ".." that you see when you do ls -a.
