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>
