REGISTER_NETDEVICE(9) Network device support REGISTER_NETDEVICE(9)NAME
register_netdevice - register a network device
SYNOPSIS
int register_netdevice(struct net_device * dev);
ARGUMENTS
dev
device to register
DESCRIPTION
Take a completed network device structure and add it to the kernel interfaces. A NETDEV_REGISTER message is sent to the netdev notifier
chain. 0 is returned on success. A negative errno code is returned on a failure to set up the device, or if the name is a duplicate.
Callers must hold the rtnl semaphore. You may want register_netdev instead of this.
BUGS
The locking appears insufficient to guarantee two parallel registers will not get the same name.

device_create_vargs - creates a device and registers it with sysfs
SYNOPSIS
struct device * device_create_vargs(struct class * class, struct device * parent, dev_t devt, void * drvdata, const char * fmt,
va_list args);
ARGUMENTS
class
pointer to the struct class that this device should be registered to
parent
pointer to the parent struct device of this new device, if any
devt
the dev_t for the char device to be added
drvdata
the data to be added to the device for callbacks
fmt
string for the device's name
args
va_list for the device's name
DESCRIPTION
This function can be used by char device classes. A struct device will be created in sysfs, registered to the specified class.
A "dev" file will be created, showing the dev_t for the device, if the dev_t is not 0,0. If a pointer to a parent struct device is passed
in, the newly created struct device will be a child of that device in sysfs. The pointer to the struct device will be returned from the
call. Any further sysfs files that might be required can be created using this pointer.
Returns struct device pointer on success, or ERR_PTR on error.
NOTE
the struct class passed to this function must have previously been created with a call to class_create.
