close_task
close_task — closes a task opened by locate_task.
Arguments
- task
A task descriptor as assigned to a
locate_task
call.
Returns
t if the task could
be closed, else nil.
Description
When a task is opened (located) for interprocess
communication, a communication link may be established.
This link must be cleaned up if it is to be re-used.
There is no hard limit to the number of tasks which may be
open with QNX 4 message passing, but TCP/IP exerts an
operating system-dependent limit on the number of
simultaneously open tasks. Tasks will automatically be
closed by the garbage collector when they are no longer
referenced.
Example
Gamma> task = locate_task("Task 1",nil);
#<Task:9684>
Gamma> close_task(task);
t
Gamma>
