`locate_task_id`

locate_task_id — finds and connects to tasks by task ID and network node.

Syntax

locate_task_id (task_id, node_id, channel_id, async_reqd)

Arguments

task_id: The task ID for this task (as a number).
node_id: The network node number for this task.
channel_id: The task ID for this task. This is required for QNX 6, ignored in QNX 4 and Linux.
async_reqd: t if locate_task should automatically call init_async_ipc for this task.

Returns

A task if successful, otherwise nil.

Description

This function makes a TCP/IP connection or QNX 4 virtual circuit to the named task based on the task_id and the node number on which the task is running. If async_reqd is t, then init_async_ipc is also called. If the node number is zero, the current node is used.

Example

Task 1:

Gamma> init_ipc("Task 1","14");
t
Gamma> getpid();
9271
Gamma>

Task 2:

Gamma> init_ipc("Task 2","25");
t
Gamma> locate_task_id(9271,1,nil);
#<Task:9271>
Gamma>
