Access to the character device is performed through the device name in the file system. Those device names are simply nodes that are called file system trees, and they are typically located in the/dev directory. Device files for character device drivers can be identified by
Access to the character device is done through the device name in the file system. Those device names are simply nodes that are called file system trees, and they are typically located in the/dev folder.Device files for character device drivers can be identified by ' C ' in the first column of the ls-l command output.
