I have just created a loadable kernel module using C.
I followed a guide that make me use the module_init and module_exit macros.
Here is the code:
#include <linux/init.h>
#include <linux/kernel.h>
#include <linux/module.h>
/* This function is called when the module is loaded. */
int simple init(void)
printk(KERN INFO "Loading Modulen");
return 0;
/* This function is called when the module is removed. */
void simple exit(void)
printk(KERN INFO "Removing Modulen");
/* Macros for registering module entry and exit points. */
module init(simple init);
module exit(simple exit);
MODULE LICENSE("GPL");
MODULE DESCRIPTION("Simple Module");
MODULE AUTHOR("SGG");
My question is:
- Once a connect the module to the kernel, which is the method entry point of the file? In fact there is no main method.
- In which way the kernel is able to call the methods in the file?
- How , using the libraries, we succeed in connecting the file to the kernel?
