Example in C The following pages give the source code for the event-retrieval program in C.
/*-----------------------------------------------------------
*
* File: EXEMSC1
*
* This program demonstrates how to retrieve an event
* message produced by the OSI/AS subsystem and handle it
* appropriately. It does the following:
*
* - Starts and opens an EMS consumer distributor.
*
* - Prompts you at your terminal for a filter file name.
* The filter file name must be entered in full
* path-name form, separated by spaces--for example,
* "$myvol mysvol fltr1".
*
* - Connects the collector $0 and loads a filter file
*
* - Performs the following steps in a loop:
* -- Issues a GETEVENT command
* -- Displays an event message at your terminal
*
* The program waits for new event messages that pass the
* specified filter and displays them as they arrive.
*
* To terminate the program, press the BREAK key
* and type STOP.
