How can I use 'ctags' ?
Hi friends,
How can I use ctags in linux device driver. consider a program 1. #define DEV_NAME "TEST" 2. struct file_operations char_fops = {}; 3. int major; 4. static int char_init() { 5. major = register_chrdev(0,DEV_NAME,&char_fops); 6. if(major < 0) { 7. printk(KERN_ALERT"Device registration failed\n"); 8. return -ENODEV; 9. } 10. printk(KERN_ALERT, major); 11. return 0; 12. } 13. static void char_exit() { 14. int ret; 15. ret = unregister_chrdev(major, DEV_NAME); 16. if(ret < 0) { 17. printk(KERN_ALERT, ret); 18. } 19. } 20. module_init(char_init); 21. module_exit(char_exit); 22. MODULE_LICENSE("GPL"); Consider the above program, If I want to see the function 'register_chrdev' which is in header file. How can I see this. Please give me step by step process. Thanks in advance.
