Event Dictionary

B.1 Introduction

This chapter provides a "dictionary" of the events collected by WindView. It lists each event by object type (message queue, semaphore, task, and so on), providing the following information for each:

The event icon.

The possible causes of the event, including which type of code (system, application, or ISR) could have caused it.

Any task state effects that can result from the event.

The information collected about the event for each event-logging level. (That is, the information displayed when you double-click on the event icon or otherwise inspect it with the Show Event dialog box; see The Show Event Dialog Box for details on using this window.)

Table B-1 shows the paradigm that Wind River Systems used to create the default WindView icons.

NOTE: The following are not supported by WindView (that is, they are not instrumented and so do not show up in a WindView event log): VxMP shared objects (shared semaphores and message queues), and VxWorks 4.0.x-style semaphores.
