Struct axtask::CurrentTask

pub struct CurrentTask(/* private fields */);

Available on crate feature multitask only.

A wrapper of AxTaskRef as the current task.

It won’t change the reference count of the task when created or dropped.

Implementations

impl CurrentTask

pub fn as_task_ref(&self) -> &AxTaskRef

Converts CurrentTask to AxTaskRef.

Methods from Deref<Target = TaskInner>

pub fn id(&self) -> TaskId

Gets the ID of the task.

pub fn name(&self) -> &str

Gets the name of the task.

pub fn id_name(&self) -> String

Get a combined string of the task ID and name.

pub fn join(&self) -> Option<i32>

Wait for the task to exit, and return the exit code.

It will return immediately if the task has already exited (but not dropped).

pub unsafe fn task_ext_ptr(&self) -> *mut u8

Returns the pointer to the user-defined task extended data.

Safety

The caller should not access the pointer directly, use TaskExtRef::task_ext or TaskExtMut::task_ext_mut instead.

pub fn kernel_stack_top(&self) -> Option<VirtAddr>

Returns the top address of the kernel stack.

Trait Implementations
