Programming Tasks

DEVELOPER

For a third party application to execute a Task, it must use the services provided in P4API to carry out the following steps:

• Connection to a PROIV Virtual Machine on the appropriate machine. If the kernel is not already running, start it up.

• Passing of logon information to the PROIV Virtual Machine.

• Passing of Task name and parameters to the PROIV Virtual Machine.

• Causing the Task to be executed.

• Receiving output parameters from the Task.

• Receiving error information back from the Task and/or Bus.

In addition, the PROIV Virtual Machine must do the following:

• Determine when to stop executing function links so that only the particular functions that belong to a Task are executed.

• When a Task is finished, wait on the Bus to get instructions.
