class TaskEnumerator

Defined at line 51 of file ../../zircon/system/ulib/task-utils/include/task-utils/walker.h

Interface for walking a job tree.

Public Methods

zx_status_t OnJob (int depth, zx_handle_t job, zx_koid_t koid, zx_koid_t parent_koid)

Each of these methods visits the corresponding task type. If any On*()

method returns a value other than ZX_OK, the enumeration stops. See

|task_callback_t| for a description of parameters.

zx_status_t OnProcess (int depth, zx_handle_t process, zx_koid_t koid, zx_koid_t parent_koid)

zx_status_t OnThread (int depth, zx_handle_t thread, zx_koid_t koid, zx_koid_t parent_koid)

zx_status_t WalkJobTree (zx_handle_t root_job)

Walks the job/process/task tree rooted in root_job. Visits tasks in

depth-first pre order.

zx_status_t WalkRootJobTree ()

Calls WalkJobTree() on the system's root job. Will fail if the calling

process does not have the rights to access the root job.

TODO(dbort): Add a different lib/API to get the system root job and

remove this function.

bool has_on_job ()

Subclasses must overload these to indicate which task types to actually

visit. Avoids, e.g., visiting every thread in the system when a caller

only cares about jobs.
