init_ipc
init_ipc — sets up necessary data structures for IPC.
Syntax
init_ipc (my_name, my_queue_name?, domain?)
Arguments
- my_name
- A name for this task, as a string.
It is only used internally.
- my_queue_name
- Optional queue name for this task, as
a string. This is necessary for asynchronous
communication, and it must be unique on the
system.
- domain
- Optional domain name for this
task.
Returns
t on success,
otherwise nil.
Description
Sets up all of the data structures needed prior to attempting
any interprocess communication from this task. Messages can be
neither sent nor received before this call is made. All
Cogent DataHub functions use IPC. If the value of
my_queue_name is nil, no queue name is
assigned and no asynchronous IPC is possible.
Example
Gamma> init_ipc("myname","myqueue");
t
Gamma>
