## Overview

### Methods

Public | `function GetTasksCount: NativeUInt;`
Public | `function GetTaskIdsList(var task_ids: TCefCustomInt64Array): boolean;`
Public | `function GetTaskInfo(const task_id: int64; var info: TCustomTaskInfo): boolean;`
Public | `function KillTask(task_id: int64): boolean;`
Public | `function GetTaskIdForBrowserId(browser_id: Integer): int64;`

## Description

### Methods

Public | `function GetTasksCount: NativeUInt;`
Returns the number of tasks currently tracked by the task manager. Returns 0 if the function was called from the incorrect thread. ###### Attributes GUID['{913B6FE7-1543-407D-9A23-8C232103965B}']

Public | `function GetTaskIdsList(var task_ids: TCefCustomInt64Array): boolean;`
Gets the list of task IDs currently tracked by the task manager. Tasks that share the same process id will always be consecutive. The list will be sorted in a way that reflects the process tree: the browser process will be first, followed by the gpu process if it exists. Related processes (e.g., a subframe process and its parent) will be kept together if possible. Callers can expect this ordering to be stable when a process is added or removed. The task IDs are unique within the application lifespan. Returns false (0) if the function was called from the incorrect thread.

Public | `function GetTaskInfo(const task_id: int64; var info: TCustomTaskInfo): boolean;`
Gets information about the task with |task_id|. Returns true (1) if the information about the task was successfully retrieved and false (0) if the |task_id| is invalid or the function was called from the incorrect thread.

Public | `function KillTask(task_id: int64): boolean;`
Attempts to terminate a task with |task_id|. Returns false (0) if the |task_id| is invalid, the call is made from an incorrect thread, or if the task cannot be terminated.

Public | `function GetTaskIdForBrowserId(browser_id: Integer): int64;`
Returns the task ID associated with the main task for |browser_id| (value from cef_browser_t::GetIdentifier). Returns -1 if |browser_id| is invalid, does not currently have an associated task, or the function was called from the incorrect thread.
