Detailed Description

The device class provides methods for interacting with devices.

It is different from the file class only in that it provides a method to create a device node and that by default, the device class does not query the device for parameters (such as size) when it is opened but the file class does. Querying a device node for parameters can have unexpected effects.

Constructor & Destructor Documentation

◆ device()

device::device ( )

Creates an instance of the device class.

◆ ~device()

virtual device::~device ( )

virtual

Deletes this instance of the device class.

Member Function Documentation

◆ createDeviceNode()

static bool device::createDeviceNode	(	const char *	filename,
		bool	blockdevice,
		uint16_t	major,
		uint16_t	minor,
		mode_t	perms )

static

Creates device node "filename" with major number "major" and minor number "minor". The device node will be created as a block device if "blockdevice" is true, otherwise it will be created as a character device. The device node will be assigned permissions "perms". Returns true on success and false on failure.
