Struct kernel::miscdev::Registration[][src]

pub struct Registration<T: Sync = ()> {
    pub context: T,
    // some fields omitted
}
Expand description

A registration of a miscellaneous device.

Fields

context: T

Context initialised on construction and made available to all file instances on FileOpener::open.

Implementations

Creates a new Registration but does not register it yet.

It is allowed to move.

Registers a miscellaneous device.

Returns a pinned heap-allocated representation of the registration.

Registers a miscellaneous device with the rest of the kernel.

It must be pinned because the memory block that represents the registration is self-referential. If a minor is not given, the kernel allocates a new one if possible.

Trait Implementations

Removes the registration from the kernel if it has completed successfully before.

The type of argument this adapter extracts.

Converts untyped data stored in [struct inode] and [struct file] (when [struct file_operations::open] is called) into the given type. For example, for miscdev devices, a pointer to the registered [struct miscdev] is stored in [struct file::private_data]. Read more
