#[repr(transparent)]
pub struct File(_);
Expand description

Wraps the kernel’s struct file.

Invariants

Instances of this type are always ref-counted, that is, a call to get_file ensures that the allocation remains valid at least until the matching call to fput.

Implementations

Constructs a new [struct file] wrapper from a file descriptor.

The file descriptor belongs to the current process.

Returns the current seek/cursor/pointer position (struct file::f_pos).

Returns the credentials of the task that originally opened the file.

Returns the flags associated with the file.

The flags are a combination of the constants in flags.
