As Linux has turned out to be one of the most popular operating systems used, the interest in developing proprietary device drivers has also increased. When a device is connected to the system, a device file is created in /dev directory. A driver’s probe() may return a negative errno value to indicate that the driver did not bind to this device, in which case it should have released all resources it allocated: It is open source as its source code is freely available. These files are grouped into the /dev directory, and system calls open, read, write, close, lseek, mmap etc. Linux is primarily divided into User Space & Kernel Space.
