the code of the module that i written is as follows:
#define MODULE
#include <linux/module.h>
#include <linux/proc_fs.h>
#define MODULE_NAME "manti"
struct manti
{
char mm[20];
};
static struct proc_dir_entry *example_dir;
struct manti m1;
int init_module(void)
{
example_dir=proc_mkdir(MODULE_NAME,NULL);
if(example_dir==NULL)
{
printk("<1> error in creation of proc file\n");
}
else
printk("<1>success in creation of proc dir\n");
}
void cleanup_module(void)
{
remove_proc_entry(MODULE_NAME,NULL);
printk("<1>proc entry removed\n");
}
here iam just making one directory in the proc file named manti
i am trying to compile it like
gcc -c proc.c
where the kernel version is 2.4.20-8
but i am getting following errors
