Sample text
This is fine if you want to do something the kernel programmers thought you'd want, such as write a device driver. But what if you want to do something unusual, to change the behavior of the system in some way? Then, you're mostly on your own. This is where kernel programming gets dangerous. While writing the example below, I killed the open() system call. This meant I couldn't open any files, I couldn't run any programs, and I couldn't shutdown the computer. I had to pull the power switch. Luckily, no files died.
Put_user(*(Message_Ptr++), buffer++); length−−; bytes_read++; } #ifdef DEBUG printk(KERN_INFO "Read %d bytes, %d left\n", bytes_read, length); #endif /* * Read functions are supposed to return the number * of bytes actually inserted into the buffer */ return bytes_read; } /* * This function is called when somebody tries to * write into our device file. */ static ssize_t device_write(struct file *file, const char __user * buffer, size_t length, loff_t * offset) { int i; #ifdef DEBUG printk(KERN_INFO "device_write(%p,%s,%d)", file, buffer, length); #endif for (i = 0; i < length && i < BUF_LEN; i++) Chapter 7.
So to help people writting /proc file, there is an API named seq_file that helps formating a /proc file for output. It's based on sequence, which is composed of 3 functions: start(), next(), and stop(). The seq_file API starts a sequence when a user read the /proc file. A sequence begins with the call of the function start(). If the return is a non NULL value, the function next() is called. This function is an iterator, the goal is to go thought all the data. Each time next() is called, the function show() is also called.
