kernel modules....................

one small doubt....
i wrote the following code in 2.4.20
then recomplied the kernel to 2.4.20 custom..
hello all,
now i tried to compile and insert the module....

the module is getting inserted ,but whatever print msg i have given is not getting printed....( i think the static int hello(void)
itself is not getting called when i load the module)

#include <linux/init.h>
#include <linux/kerenel.h>
#include <linux/module.h>
#include "/root/proj_code/check.c" // some file...........

extern void check(void);

void (*check_ptr)(void) = NULL:

static int hello(void)
check_ptr = check;
printk("\n some message \n ");

return 0;

static void hello_out(void)



why is this problem , any idea.....?

I got it working. With removal of some errors in your pasted code. i hope you already have got those errors and solved it. I did dmesg and last few lines showed me printk messages. also you can checl
tail -f /var/log/messages to check printk messages
